The perimeter of a rectangle is 48 inches. If the width of the rectangle is 8 inches, what is the length?

16 inches

Step-by-step explanation:

A rectangle has two pairs of equal sides. The known width of this rectangle is 8 inches, so two of the four sides are 8 inches long, which add up to 16 inches. To find the length of the rectangle, find the remaining perimeter and divide it into two equal parts. 48 - 16 is 32, so the two lengths of the rectangle add up to equal 32. To find the length of one side length, divide 32 by 2. 32/2 is 16, so the length of the rectangle is 16 inches.

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
