Answer:

D. 12 feet

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

Where L is length and W is the width.

Given

perimeter = 82 feet

Length is 5 more than 2w

That’s L = 5 + 2w

Now substitute 5 + 2w for L in the formula above

We have

82 = 2 ( 5 + 2w + w)

Simplify the bracket

82 = 2(5 + 3w)

Distribute 2 into (5 + 3w)

82 = 2 x 5 + 2 x 3w

82 = 10 + 6w

Subtract 10 from both sides

82 - 10 = 10 - 10 + 6w

72 = 6w

Divide both sides by 6

72/6 = 6w/6

12 = w

W = 12 feet

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=11\ years\\ P=\$7,900\\r=5.5\%=5.5/100=0.055$

substitute in the formula above

$A=7,900(1+0.055*11)$

$A=7,900(1.605)$

$A=\$12,679.50$
