Answer:

width = 15 inches

length = 36 inches

Step-by-step explanation:

To solve you need to find the width...

width = w

length = 2w + 6

the perimeter is all the way around the area, so..

2w + 2(2w + 6) = 102

because there are 2 widths and 2 lengths in a perimeter.

Solve for w:

2w + 4w + 12 = 102

subtract 12 from both sides and combine like terms...

6w = 90

divide both sides by 6...

w = 15

the width = 15, and the length = 2(15) + 6 = 36

nika2105 [10]

Given data:

The given expression is an=-3+5(n-1).

The given expression can be written as,

$\begin{gathered} a_n=-3+5(n-1) \\ =-3+5n-5 \\ =-8+5n \end{gathered}$

Thus, the explicit formula for the function is F(n)=-8+5n.
