A. 33%
B. 96%
C. 70%
D. 30%

a.33% b.96% c.70% d.30%      

Step-by-step explanation:

D 30%

Step-by-step explanation:

First you subtract 224 from 320 to get the difference which is 96

you then divide 320 by 96 to get the decimal and multiply it by 100 to get the percent

Step-by-step explanation:

You are multiplying x² - 4x + 4 and 6x + 3.

This is set up like:

6x + 3(x² - 4x + 4)

To solve this, we want to multiply each term that is outside of the parentheses with each term that is inside of the parentheses.

Let's start with 6x.

6x • x² = 6x³

6x • -4x = -24x²

6x • 4 = 24x

These numbers will be in the first blank row.

Now, let's move onto 3.

3 • x² = 3x²

3 • -4x = -12x

3 • 4 = 12

These numbers will be in the second blank row.

Now let's write all these numbers together.

6x³ - 24x² + 24x + 3x² - 12x + 12

Combine like terms, pay attention to the exponent.

6x³ - 21x² + 12x + 12

Refer to the completed table below.

Hope this helps!
