Answer:

16x -2

Step-by-step explanation:

You know how to compute the perimeter of a rectangle of length L and width W:

P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

P = 2((5x-2) +(3x+1))

P = 2(8x -1)

P = 16x -2 . . . the perimeter of the rectangle

25 x .15 = 3.75
25 - 3.75 = 21.25
21.25 x .20 = 4.25
21.25 - 4.25 = $17 total

Let garret’s age be x

x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16

Garrett’s age after two years = 16 + 2 = 18
