it is 9 inches tall
Step-by-step explanation:
p=2L + 2W
28=2L + 2 x 5
28=2L +10
28-10=2L
18=2L
L=9
Answer:
9 inches.
Step-by-step explanation:
Since the width of the rectangle is 5 inches, We have to times it by 2 which is 10.
Then deduct it from the perimeter of 28, which equals to 18. We have to divide it by 2 so we can find out how tall each side is. 18 divided by 2=9.

Here's one way to do it
Step-by-step explanation:
You can use a number line for the subtraction of integers.
Subtracting a negative number is the same as adding its opposite; you move to the right on the number line.
The opposite of -8 is +8, so
2 - (-8) is the same as 2 + 8.
Start at 2 and move 8 units to the right.
See the number line below.
2 - (-8) = 10
