Answer:
[tex]B. 4x^2+20x+25[/tex]
Step-by-step explanation:
The length of the side:
[tex]2x+5[/tex]
In a square all sides have the same length.
And the area of a square is given by the formula:
[tex]Area=(length)^2[/tex]
so, substituting that the length is [tex]2x+5[/tex]
[tex]Area=(2x+5)^2[/tex]
and we solve this squared binomial with the formula:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
in this case [tex]a=2x[/tex] and [tex]b=5[/tex]
thus, we get:
[tex]Area= (2x)^2+2(2x)(5)+(5)^2[/tex]
and solving:
[tex]Area=4x^2+20x+25[/tex]
which is option B.
What is the coordinate rule for a dilation centered at (0,0) with a scale factor of 3?
15 POINTS
No picture given.
Answer: (0,0)
Step-by-step explanation:
To find the scale factor of coordinates, you have to multiply the x and y by the scale factor, which is 3.
0 × 3 = 3
0 × 3 = 3
Answer is (0,0)
The rule would be : (x, y) --> (3x, 3y).
The coordinate rule for a dilation centered at (0,0) with a scale factor of 3 is (x', y') = (3x, 3y).
Explanation:A dilation is a transformation that changes the size of a figure without altering its shape. The coordinate rule for a dilation centered at (0,0) with a scale factor of 3 is given by the equation:
(x', y') = (3x, 3y)
This means that each coordinate of the original figure is multiplied by the scale factor to find the corresponding coordinate of the dilated figure.
Jessica owns a base salary of $150 every week with an additional 40% commission on everything she sells if Jessica is sold $1650 worth of items last week what was her total pay?
Answer:$2,310
You set up dash equals dash 1,650 over 100% and x over 140% you would then cross multiply and divide. You would multiply 1,650 and 140 which give you 231000 the divide that by 100 and that gives you $2,310
The volume of a cube can be found using the equation V=S3, where V is the volume and Sis the measure of one side of the cube. Match the equation for how to solve for the side length of a cube to its description.
Answer:
s = ∛729 in³
Step-by-step explanation:
Since the volume is 729 in³, our equation can be plugged into:
729 = s³.
Isolate s by cube rooting each side: ∛729 = s.

C.
How many chocolates did Bertha sell today?
D.
How many students are there in Kathy's class?
Answer:

Answer:
B. What are the shoe sizes of players on the soccer team?
Step-by-step explanation:
A statistical question is one that can be answered by collecting data and where that data will vary.
We do not need to collect data to determine the number of questions on Ben's math test.
There is no variability in the number of chocolates Bertha sells in one day, nor in the number of students in Kathy's class.
To determine the shoe sizes of players on the soccer team, we must collect the data and the data will vary from player to player. This is the statistical question.

lliana cubed the number of flowering plants in her garden, then added 2 vegetable plants. Let p represent the original number
of plants in her garden. Which shows an expression to represent the total number of plants in her garden and the total number
of plants if p= 3?
Answer:
29
Step-by-step explanation:
if p=3, then as the question asks, we must cube it and add 2.
3 cubed is 27, plus 2 is 29.
T=29
where t is the total number of plants.

[tex]2x^{4}+x^{3}-x+2[/tex]
Step-by-step explanation:
To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.
[tex]x^{3}+3x^{2}-2x-6[/tex]
[tex]x^{3}+3x^{2}[/tex]and[tex]-2x-6[/tex]
[tex]x^{2}(x+3)[/tex]and[tex]-2(x+3)[/tex]
So this one is not prime, since you can still factor it.
[tex]x^{3}+2x^{2}-3x-6[/tex]
[tex]x^{3}+2x^{2}[/tex]and[tex]-3x-6[/tex]
[tex]x^{2}(x-2)[/tex]and[tex]3(x-2)[/tex]
So this one is not prime, since you can still factor it.
[tex]4x^{4}+4x^{2}-2x-2[/tex]
[tex]4x^{4}+4x^{2}[/tex]and[tex]-2x-2[/tex]
[tex]4x^{3}(x+1)[/tex]and[tex]-2(x+1)[/tex]
So this one is not prime, since you can still factor it.
[tex]2x^{4}+x^{3}-x+2[/tex]
[tex]2x^{4}+x^{3}[/tex]and[tex]-x+2[/tex]
[tex]x^{3}(2x+1)[/tex]and -x+2 cannot be further factored.
Therefore, [tex]2x^{4}+x^{3}-x+2[/tex] is a prime.

dentify the percent, amount, and base in this problem. 75% of what number is 30?
Answer:
40
Step-by-step explanation:
This is essentially just (4/3), or [tex]\frac{3}{4}^{-1}[/tex]. (4/3)*30 = 40, so our answer must be 40. Just to check, taking 75 percent of 40, we indeed get 30!
For this case we must find a number of which 30 represents 75%. For this, we make a rule of three:
x ------------> 100%
30 ----------> 75%
Where the variable "x" determines the base number of which 30 is 75%
[tex]x = \frac {100 * 30} {75}\\\\[/tex]
[tex]x=40[/tex]
Thus, 30 represents 75% of 40.

40

if a and b are real numbers and if a>b and b =7 then >_ 8. Which Of the following is a counterexample to the assertion above?
A) a=6.5
B) a = 7.5
C) a= -8.5
D) a=8.1
Answer:
B
Step-by-step explanation:
if a is greater then b and b=7 and A< 8 7.5 is the only one that fits the description
Option B) a = 7.5 is the correct
The question is asking which option is a counterexample to the assertion that if a and b are real numbers with a > b and b = 7, then a ">=_" 8. To find a counterexample, we need an instance where a is greater than b (which is 7), but a is not greater than or equal to 8.
A) a=6.5 cannot be the correct answer because it is not greater than b. B) a = 7.5 is indeed greater than b=7, but it is less than 8 which makes it the correct counterexample. Both C) a= -8.5 and D) a=8.1 are not counterexamples; the former is less than b, and the latter is greater than 8.
Therefore, option B) a = 7.5 is the correct counterexample because it satisfies the condition a > 7 but does not meet the incorrect assertion that a is also ">=_" 8.
