Jason designs a rectangular sandbox. He models the perimeter of the sandbox using the expression 8l+2, where l is the length of the sandbox. Which statement includes an equivalent expression to 8l+2 with a correct description? A. The expression 2l+2(3l+1) shows the width is 1 more than 3 times the length.
B. the expression 10l shows the perimeter is 10 times the length.
C. The expression 2l+(6l+2) shows the width is 2 more than 6 times the length.
D. The expression 2(4l+1) shows the perimeter is 1 more than 4 times the length.

A   .The expression 2l+2(3l+1) shows the width is 1 more than 3 times the length.

Step-by-step explanation:

p = 8l + 2

Length = l

Width:

2w = p - 2l

2w = (8l + 2) - 2l

2w = 6l + 2

w = 3l + 1

Therefor w is 3 times the length plus 1

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
