That both sides are 5 what is the length

7 inches

Step-by-step explanation:

I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l

let P represent the perimeter of the window in inches

let w represent the width of the window in inches

let l represent the length of the widow in inches

(L is l whereas one is 1)

So we know w=5 and P=24

This lets us have the equation 24= 2 x 5 + 2l

24=10 + 2l

14=2l

7=l

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
