Answer:

C -16x + 74/5

Step-by-step explanation:

2(x + 7) - 18x + (4/5)

Expand the brackets.

2x + 14 - 18x + (4/5)

Combine like terms.

(2x - 18x) + (14 + (4/5))

-16x + 14 4/5

Convert 14 4/5 to an improper fraction

14 4/5 = ((14 * 5) + 4) / 5 = 74 / 5

Answer = -16x + 74/5

ANSWER

(2). 88.5 ft²

EXPLANATION

The parachute is in the form of a semicircle, so the area of the entire parachute can be calculated using the formula,

Area=½ πr²

The radius is 13cm.

We substitute the radius to get

$Area= \frac{1}{2} \pi \times {13}^{2}$

$= 265.46457922834 \: \: {ft}^{2}$

The company required that, each parachute be made from equal parts of red, white, and blue fabric.

Hence, the fabric of each color needed is

$= \frac{265.46457922834}{3} = 88.4882$

To the nearest tenth, we have,

$= 88.5 {ft}^{2}$
