Answer the 4 questions please.

Answer    1:Length: 9 inches

Width: 3 inches

Explanation:

You use the information given to you to write a system of two equations.

The perimeter of a rectangle is equal to the sum of its length and its width, multiplied by

2

P

=

2

⋅

(

L

+

w

)

In your case, you know that

2

(

L

+

w

)

=

24

This will be your first equation.

Now focus on the fact that its length is 3 times greater than its width. This can be written like this

L

=

3

⋅

w

Your system will be

{

2

(

L

+

w

)

=

24

L

=

3

w

To solve for the length and width of the rectangle, use the expression you have for

L

in the first equation to get

w

2

⋅

(

3

w

+

w

)

=

24

2

⋅

4

w

=

24

⇒

w

=

24

8

=

3

This means that

L

is equal to

L

=

3

⋅

3

=

Step-by-step explanation:    2

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
