The area painted red on one of the front wheels on DeMarius’ car will be 80.42 inches².

<h3>How to calculate the area?</h3>

From the information given, the The front wheels on DeMarius’ car are divided into sectors of equal area and the radius of each wheel is 8 inches. The area will be:

= 2/5 × πr²

= 0.4 × 3.14 × 8²

= 80.42 inches²

The radius, in feet, of a rear wheel on the car will be:

r1(2π) = r2(2π)

8(2π) = r2(8/5)(2π)

16 = r2(8/5)

r = 5/8 × 16

r = 10 inches

r = (5/6) feet

Answer:

Given equation: 2(x+7) = 36.                ......[1]

Distributive Property of multiplication states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,

a \cdot (b+c) =a\cdot b+ a\cdot c

Then,

By using the distributive property in equation [1];

2(x+7) = 36

(2 \cdot x) + (2 \cdot 7) =36

Simplify:

2x+14=36

Divide both sides by 2 in above equation:

\frac{2x+14}{2} =\frac{36}{2}

Simplify:

x+7 = 18.

Therefore, the first correct step would be option B,

after that the next step would be option A then option F as shown above;

Remaining options are not enough information to solve the given equation  2(x+7) = 36.
