40 = -5 × \frac{n}{8}

First, simplify 5 × \frac{n}{8} to \frac{5n}{8} / Your problem should look like: 40 = -\frac{5n}{8}
Second, multiply both sides by 8. / Your problem should look like: 320 = -5n
Third, divide both sides by -5. / Your problem should look like: \frac{320}{-5} = n
Fourth, simplify \frac{320}{-5} to - \frac{320}{5} / Your problem should look like: -\frac{320}{5} = n
Fifth, simplify \frac{320}{5} to 64. / Your problem should look like: -64 = n
Sixth, switch sides. / Your problem should look like: n = -64

Answer: n = -64

Kayla has a deck that measures 4 feet by 21 feet.
Flura [38]

For the area of the deck to be doubled, he should increase each dimension by 3.

<h3>How to find the dimension increase to double the area?</h3>

The deck is 4 feet by 21 feet.

She wants to increase each dimension by equal lengths so that its area is doubled.

Therefore,

initial area = 4 × 21 = 84 ft²

Hence,

The increase by equal length

width = x + 4

length = x + 21

area = 2(84) = 168 ft²

Therefore,

(x + 4)(x + 21) = 168

x² + 21x + 4x + 84 = 168

x² + 25x + 84 = 168

x² + 25x + 84 - 168 = 0

x² + 25x - 84 = 0

(x + 28) • (x - 3)  = 0

x = -28 or 3

It can only be positive.

Therefore, she should increase each dimension by 3.
