First we have to combine like terms. 4x² is one term. -8x is another term. -7 is another term. poly = "many" ⇒ polynomial = many terms
(4x² - 8x - 7) + (-5x + 16)
4x² - 8x - 7 - 5x + 16
Combine like terms.
Step 1: 4x² has no other terms with x² so it stays by itself.
Step 2: -8x and -5x are like terms because they both have x.
So -8x -5x = -13x (You put two negatives together)
Step 3: -7 and 16 don't have any x with them. -7 + 16 = 16 - 7 = 9
Now we put all the answers of the steps together.
Step 1: 4x²
Step 2: -13x
Step 3: 9
So the answer is 4x² - 13x +9
And it's a polynomial because there are three terms = "more than one term"
24 cm would be my answer to this.

Answer:
18ft^2
Step-by-step explanation:
I'm going to use a dilation method to help solve this.
First we need to find your base. So 12/4 = 3.
6*3 = 18.
18 ft^2
