First, we are going to want to plug in the values we are given. In this case, we will end up with the equation:

From here, we can solve the equation to find
:

- Apply the commutative property to rearrange the terms on the right-side of the equation to make the distributive property more apparent

- Apply the distributive property

- Subtract 8 from both sides of the equation

- Divide both sides of the equation by -2
We have found that c = 1.
The answer to the question is B
Hope this helps :)
Step-by-step explanation:
area of missed triangle =1/2×2×4=4 cm2
area of whole rectangle =4×8=32 cm2
area of shape =32_4 =28cm2
Answer is G
with or without the 10, you are going to get 5 as your answer to the equation
