Answer: 1

Step-by-step explanation:

Find (d + c)(3) The x value is 3 so you plug in 3 for the x's in the equation

d(x) = 2x − 4

d(3) = 2(3) - 4

d(3) = 2

c(x) = 2x − 7

c(3) = 2(3) - 7

c(3) = -1

Now you plug in the value of d and c into your original equation which is (d+c)(3)

(2 + (-1)) = 1

This means (d+c)(3) = 1

Answer:

I don`t really know the math behind it but the answer is

<u>Area = 10 units</u>

If you take the triangle on the right side and put it on the left it makes another full two units, so it`s 10.

Sorry if you needed work shown, I can research if ya need it.
