Answer:

h = -8/5

Step-by-step explanation:

21 = -4h +13-h

simplify the right side

21 = -5h + 13

subtract 13

21 = -5h + 13

-13          - 13

8 = -5h

divide by -5

8 = -5h

/-5  /-5

-\frac{8}{5}  = h

The perimeter of a rectangle is 102 inches. The length is 5 inches greater than the width.
Mazyrski [523]

Answer:

w = 23

l = 28

Step-by-step explanation:

w = width

l = w+5

P = 2 (l+w)

102 = 2( w+5+w)

102 = 2(2w+5)

Divide each side by 2

51 = 2w+5

Subtract 5

46 = 2w

Divide by 2

23 = w

The width is 23 and the length is 23+5 = 28
