Answer:

2x² +2x - 12

Step-by-step explanation:

area of rectangle = length X width

length = x+3

width = 2x - 4

Area = (x+3)(2x-4)

        = x(2x-4) +3(2x-4)

        = 2x² - 4x + 6x - 12

        = 2x² +2x - 12

In 1819, the United States purchased Florida from Spain for
Flura [38]

Answer:

<h3>D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

<em>x = $0.76*10²</em>

<em />

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴
