Answer: 7x+12876ba−8584b+57942a−38628

Step-by-step explanation:

7x + (1073 • (2b + 9) • (6a - 4))
Pull out like factors : 6a - 4 = 2 • (3a - 2)
7x + 2146 • (2b + 9) • (3a - 2)
7x + 12876ba - 8584b + 57942a - 38628

4. The length of your rectangular vegetable garden

OleMash [197]

The area of a garden is the amount of space the garden occupies

The area of the garden is (c) 375 ft^2

The given parameters are:

$L = 15 \times W$ --- Length equals 15 times width

$Perimeter=160$

The perimeter of a rectangle is:

$Perimeter= 2(L + W)$

Substitute known values

$160= 2(15 \times W + W)$

Divide through by 2

$80= 15 \times W + W$

$80= 15W + W$

$80= 16W$

Divide through by 16

$5= W$

Rewrite as:

$W =5$

The area of a rectangle is:

$Area = L \times W$

Substitute $L = 15 \times W$

$Area = 15 \times W \times W$

Substitute $W =5$

$Area = 15 \times 5 \times 5$

$Area = 375$

Hence, the area of the garden is (c) 375 ft^2
