What you want to first is substitute the numbers in for the variables in the equation

Since b= -5 , we will plug it in for -b

-5 + c = -13x

Now plug in -8 for c

-5 + (-8) = -13x

Add the numbers on the left side, which gives you -13.

-13 = -13x

Lastly, divide both sides by -13x, which will give you 1.

So x = 1

Chad is planning on painting his bedroom and the living room. His rectangular bedroom measures 10 feet by 12 feet and each wall
rosijanka [135]

Answer:

The correct answer is 3 × 5 + 3 × 7 + 6 × 7 = 78 square feet.

Step-by-step explanation:

Measures of Chad's window is 36 inches by 60 inches = 3 feet by 5 feet.

Area of the window is 15 square feet.

Measures of Chad's door is 36 inches by 84 inches = 3 feet by 7 feet.

Area of the door is 21 square feet.

Measures of Chad's closet is 72 inches by 84 inches = 6 feet by 7 feet.

Area of the closet is 42 square feet.

Equation to show the total area of window, door and closet is 15 + 21 + 42 = 78 square feet.
