Factor the polynomial: 1–bx–x+b
The polynomial 1 - bx - x + b can be factored by rearranging the terms to (1 + b) - x(1 + b), allowing us to factor out 1 + b, resulting in the factored form (1 + b)(1 - x).
Explanation:The polynomial in question, 1 \\u2212 bx \\u2212 x + b, can be factored by rearranging and grouping terms. Indeed, the suggestion to factor out at least one x from all terms that contain it can be helpful in some cases, for example, ax^2+bx+c. However, for the polynomial given, we need to rearrange the terms to (1 + b) \\u2212 x(1 + b). Notice that 1 + b can be factored out, resulting in (1 + b)(1 \\u2212 x).
Therefore, the factored form of 1 \\u2212 bx \\u2212 x + b is (1 + b)(1 \\u2212 x).
In general, when factoring polynomials, being attentive to common factors and rearranging terms to identify them can lead to a simpler expression. For a quadratic equation like ax^2+bx+c=0, factoring is a powerful tool, often applied after identifying an integrating factor or using the quadratic formula.

[tex](x - 8)(x - 5) =0 \\ \\ \therefore {x}^{2} + ( - 8 - 5) x+ ( - 8) \times ( - 5) = 0 \\ \\ \therefore {x}^{2} + ( - 13) x+ 40= 0 \\ \\ \huge \red{ \boxed{ \therefore {x}^{2} - 13x+ 40= 0 }} \\ is \: the \: required \: quadratic \: equation.[/tex]
The ________ states that if two values a and b are equal when you multiply each by the same value c, the products are equal
Answer:
The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.
Step-by-step explanation:
Multiplication property of equality:
It states that multiplying both sides of the the equation with the same constant or number then the truth value of the equation does not change.That is the equality still holds true.So, if
[tex]a = b[/tex]
Then, we can write by multiplication property of equality
[tex]a=b\\\Rightarrow a\times c = b \times c\\\Rightarrow ac = bc[/tex]
Thus, the correct answer is
The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.
Final answer:
The statement in question highlights the equality property of multiplication, which states that if two values are equal, their products with a same multiplier are also equal. This principle is fundamental in mathematics, particularly in algebra, where it underpins the manipulation and understanding of equations.
Explanation:
The statement "if two values a and b are equal when you multiply each by the same value c, the products are equal" refers to the basic principle of the equality property of multiplication in mathematics. This property underlines that if a = b, then a × c = b × c. This fundamental concept is crucial for understanding algebraic expressions and equations, where the manipulation of variables and constants is based on such properties.
For example, if we assert that 3 (number a) and 3 (number b) are equal and we choose to multiply both by 2 (number c), the resulting products, 6 and 6, are indeed equal. This example clearly illustrates how the equality of products remains consistent regardless of the multiplier, as long as the initial quantities are equal.
This principle is foundational in mathematics and serves as a cornerstone for solving equations, thereby reinforcing the understanding that equality is maintained through operations of multiplication by a constant.
What is the measure of minor arc BD?
Angle BCD is a circumscribed angle of circle A. Angle BCA
measures 40°
B
40°
© 50°
80°
100°
Answer:
[tex]minor\ arc\ BD=100^o[/tex]
Step-by-step explanation:
The picture of the question in the attached figure
we know that
A circumscribed angle is the angle made by two intersecting tangent lines to a circle
so
In this problem
BC and CD are tangents to the circle
BC=CD ----> by the Two Tangent Theorem
That means
Triangle ABC and Triangle ADC are congruent
so
[tex]m\angle BAC=m\angle DAC[/tex]
Find the measure of angle BAC
In the right triangle ABC
[tex]m\angle BAC+m\angle BCA=90^o[/tex]
substitute given value
[tex]m\angle BAC+40^o=90^o[/tex]
[tex]m\angle BAC=90^o-40^o=50^o[/tex]
Find the measure of angle BAD
[tex]m\angle BAD=2m\angle BAC[/tex]
[tex]m\angle BAD=2(50^o)=100^o[/tex]
Find the measure of minor arc BD
we know that
[tex]minor\ arc\ BD=m\angle BAD[/tex] -----> by central angle
therefore
[tex]minor\ arc\ BD=100^o[/tex]
Final answer:
The measure of the minor arc BD is d. 80°, because it is twice the measure of the inscribed angle BCA, which is 40°.
Explanation:
When we are looking for the measure of a minor arc in a circle, and we know the measure of the inscribed angle that subtends that arc, we can find the measure of the arc by understanding that the inscribed angle is half the measure of the arc it cuts from the circle. Given that angle BCA measures 40°, and assuming BCD is an inscribed angle that subtends the arc BD, we can deduce that the minor arc BD is actually twice the measure of the inscribed angle BCA.
Therefore, to find the measure of minor arc BD, we double the measure of angle BCA:
Measure of minor arc BD = 2 × measure of angle BCA
Measure of minor arc BD = 2 × 40°
Measure of minor arc BD = 80° (d.)
find the relationship between the number of shapes and the perimeter of the figure they form Write an equation to represent this relationship?
Answer:
p = 3n + 2
Step-by-step explanation:
let n be the number of shapes and p the perimeter
We can construct the following table
n : 1 2 3
p : 5 8 11
The differences in p are constant
8 - 5 = 11 - 8 = 3
Thus p = 3n + ?
n = 1 → 3(1) + ? = 5 ⇒ 3 + ? = 5 ⇒ ? = 2
n = 2 → 3(2) + ? = 8 ⇒ 6 + ? = 8 ⇒ ? = 2
n = 3 → 3(3) + ? = 11 ⇒ 9 + ? = 11 ⇒ ? = 2
We require to add 2 to 3n
Thus
p = 3n + 2

dan is building a circular swimming pool and wants the circumference to be no more than 95 feet what is the largest radius possible for the pool. Round to the nearest tenth of a foot.
The largest radius for the swimming pool is 15.1 feet
Step-by-step explanation:
Step 1:
Circumference of the circular swimming pool built by Dan = 95 feet
We need to determine the largest radius for the pool.
Step 2 :
Circle's circumference is given by 2πr
Where r represents the radius
This shows that the radius is in direct proportion to the circumference. Hence the radius corresponding to the maximum circumference will be the largest possible radius
So we have 2πr = 95
=> r = [tex]\frac{95}{2\pi }[/tex]
=> r = [tex]\frac{95}{2}[/tex] × [tex]\frac{7}{22 }[/tex] where [tex]\pi = \frac{22}{7}[/tex]
=> r = 15.1 feet (rounded off to tenth of a foot)
Step 3 :
The largest radius for the swimming pool is 15.1 feet
Final answer:
the largest radius possible for the pool, to ensure the circumference does not exceed 95 feet, is 15.1 feet.
Explanation:
Calculating the Largest Radius for a Swimming Pool
To find the largest possible radius for Dan's circular swimming pool with a circumference of no more than 95 feet, we will use the formula for the circumference of a circle, which is C = 2πr.
We need to solve for r (radius) when C ≤ 95 feet.
Setting up the equation:
95 ≥ 2πrr ≤ 95 / (2π)r ≤ 95 / (2 * 3.14) (Using π ≈ 3.14 for calculation)r ≤ 95 / 6.28r ≤ 15.1 feet (rounded to the nearest tenth)Therefore, the largest radius possible for the pool, to ensure the circumference does not exceed 95 feet, is 15.1 feet.

12 with the exponer of -6 times 12 with the exponent of -5
Answer:
[tex] {12}^{ - 11} [/tex]
Step-by-step explanation:
The expression to be simplified is
[tex] {12}^{ - 6} \times {12}^{ - 5} [/tex]
We can see that the expression involves the idea of indices.Thus,we need to consider one of the laws of indices when dealing with the expression.
One of the laws of indices states that,
[tex] {a}^{m} \times{a}^{n} = {a}^{m + n} [/tex]
This means that when multiplying indices and the bases are equal, you repeat one of the bases and add the exponents.
This implies that
[tex] {12}^{ - 6} \times {12}^{ - 5} = {12}^{ (- 6 - 5)} [/tex]
Simplifying the exponent we obtain
[tex] = {12}^{ - 11} [/tex]

There are cases where this is not true, but if you want to prove that, you'll need to know what f and g are. For example, if f(x) = x - 3 and g(x) = x2, then f(g(x)) is not equal to g(f(x)) because
f(g(x)) = x2 - 3 and g(f(x)) = (x - 3)2. Those 2 functions are not the same because f(g(0)) = -3 ≠ 9 = g(f(0)).

A group of 15 friends travel to Washington DC. 2/5 go by bus, 1/3 by metro, and the rest by car. What fraction went by car? How many people went by bus? Metro? Car?
Answer:
14 4/5 went by car.
Out of 15 friends traveling to Washington DC, 6 went by bus, 5 by metro, and 4 by car, making the fraction that went by car 4/15.
To find out how many friends traveled by each mode of transportation to Washington DC and what fraction went by car, we can follow these steps:
Calculate the number of friends that went by bus: 2/5 of 15 = 6 friends.Calculate the number of friends that went by metro: 1/3 of 15 = 5 friends. (Note that fractions of people aren't possible in real life, so we would have to adjust these numbers; for example, maybe 5 went by metro and 6 went by bus, or vice versa.)For the rest by car, subtract the number of friends who went by bus and metro from the total: 15 - 6 - 5 = 4 friends.So, the fraction that went by car is 4/15.

A truck rental company rents a truck for a one-time fee of $25 plus $1.50
per mile traveled. Kelly has $80 she can spend on the rental truck. What is
the greatest number of miles that she can travel?
Using the cost equation C = $25 + ($1.50 x M), we solve for the greatest number of miles Kelly can travel with an $80 budget, which is 36 miles after rounding down to the nearest whole number.
Explanation:To determine the greatest number of miles Kelly can travel, we use the equation provided by the truck rental company. The total cost of renting a truck is composed of a one-time fee and a per-mile charge. To begin, we subtract the one-time fee from the total budget to find out how much money is left for the per-mile charges.
The equation representing the total cost (C) for the miles (M) driven is:
C = $25 + ($1.50 × M)
Kelly has $80 to spend, so we set the total cost equal to $80:
$80 = $25 + ($1.50 × M)
Now, we solve for M:
$55 = $1.50 × M
M = $55 / $1.50
M = 36.67
Since Kelly cannot travel a fraction of a mile, we round down to the nearest whole number. The greatest number of miles Kelly can travel is 36 miles.
