The perimeter of a rectangle is 524cm. The length is is 42cm more than the width. What is the length of the rectangle?

Answers

Perimeter= 524cm
Width= 215cm
Length= 173cm
Represent L as L = W + 42.

Then P = 2W + 2L

Here, P = 524 cm = 2W + 2(W+42) = 2W + 2W + 84 = 4W + 84

Solving 524 = 4w + 84,    4W = 524-84 = 440.

Dividing both sides by 4:  W = 110 cm.  Then L = 110+42 = 152.

Check:  Does 2(110) + 2(152) = 524?  YES

W = 110 cm and L = 152 cm

The inverse of a function occurs when _____.

Answers

Final answer:

The inverse of a function occurs when the roles of x and y are interchanged, reflecting the function's graph across y = x.

Explanation:

The inverse of a function occurs when the roles of x and y are interchanged, which involves reflecting the function's graph across the line y = x. For a function to have an inverse, it must pass the horizontal line test, meaning each output value corresponds to a unique input value.

solve by factoring and show work x^2-3x-10=0

Answers

Hello there!

[tex]x^2 - 3x - 10=0 Factorize the left side (x + 2)(x-5)=0 Set factors equal to 0 x + 2 = 0 or x - 5 = 0 x = -2 or x = 5 Best of luck! [/tex]
The first rule of factoring is to try to factor a common factor from all the terms. In this case, there is no common factor.

Now we factor the trinomial.
This quadratic trinomial is of the form
x^2 + ax + b = 0
where the coefficient of the x^2 term is 1.
To factor it, find two numbers that multiply to "b", the constant term,
and add to "a", the coefficient of x.

The numbers are -5 and 2 since -5 * 2 = -10, and -5 + 2 = -3.

Now we write two sets of parentheses with x on the left side:

(x      )(x       ) = 0

We fill in the parentheses with the two numbers we found above, -5 and 2.

(x - 5)(x + 2) = 0

That is the factoring.

How many solutions does the following equation have?

Answers

The solution to the given equation is x = -1. Thus, the answer is option B exactly one solution.

How to determine the number of solutions for the equation

To determine the number of solutions for the equation 3(x + 5) = -4x + 8, simplify and solve it:

Distribute the 3 on the left side of the equation:

3x + 15 = -4x + 8

Combine like terms:

3x + 4x = 8 - 15

7x = -7

Divide both sides of the equation by 7 to isolate the variable x:

x = -1

Now, we have found a solution for the equation, which is x = -1.

Since we have found exactly one solution, the answer is (b) exactly one solution.

Ross drove 300 miles at r miles per hour and 360 miles at r+10 miles per hour. If the time needed to drive 300 miles was equal to the time needed to drive 360 miles, find the rates at which Ross drove (Express the time needed for each part of the trip as t=d/r)

Answers

For the 300 mile part:
t = d/r
t = 300/r

For the 360 mile part:
t = d/r
t = 360/(r + 10)

The times were equal, so

300/r = 360/(r + 10)

360r = 300(r + 10)

360r = 300r + 3000

60r = 3000

r = 50

r + 10 = 60

He drove 300 miles are 50 mph and 360 miles at 60 mph.

what is another way to write 4 hundreds

Answers

40 tens is another way of writing 4 hundreds because 40 tens would give you 400 and 4 hundreds also give you 400.

Another way to write 4 hundred is to express it in scientific notation which is 4.0 × 10²

Scientific notation is another way of expressing figures in standard form. It is a proper form of writing a large number in simpler ways.

Another way to 4 hundred is to express it in a standard form or scientific notation.

400 hundred in scientific notation = 4.0 × 10²

Therefore, we can conclude that 4 hundred is to express it in scientific notation which is 4.0 × 10².

X is 7 but I got m angle D wrong

Answers

Answers: 
x = 7
The measure of angle D is 14 degrees

-----------------------------------------------
-----------------------------------------------

Angle C and angle D are complementary, which means they add to 90 degrees. 

(angle C) + (angle D) = 90
(12x-8) + (3x-7) = 90
12x-8 + 3x-7 = 90
(12x+3x) + (-8-7) = 90
15x-15 = 90
15x-15+15 = 90+15
15x = 105
15x/15 = 105/15
x = 7

So you have the correct x value. Nice work.

Now use this x value to find the measure of angle D

angle D = 3*x - 7
angle D = 3*7 - 7
angle D = 21 - 7
angle D = 14 degrees

To evaluate the following expression, what steps should you do first? 7 × (4 + 16) ÷ 4 - 2

Answers

As according to PEMDAS, the step you should do first is (4+16) since it is in parentheses. Then, you do multiplication and division (order does not matter really, the two operations are on the same level so you just solve left to right) and addition and subtraction (order does not matter really, the two operations are on the same level so you just solve left to right).
1. do 4+16 which equals 20.
2. then do 7 x 20 which equals 140.
3. then divide 140 by 4 which equals 35.
4. then do 35 - 2 you'll get 33.
