Answer:

-20x³ + 0x² + 15x - 20

Step-by-step explanation:

I would have said it the other way.

"Multiply each term in the top row by -5."

 4x³ +  0x   -  3x +  4

<u>×(-5</u>)  <u>×(-5</u>)  <u>×(-5)</u>  <u>×(-5) </u>

-20x³ + 0x² + 15x -20

Malika bought 7 new pairs of shoes. Each pair of shoes cost the same amount and was discounted by $21.75.
ikadub [295]

Multiply the amount of the discount by pairs of shoes:

21.75 x 7 = 152.25

Add that to the total she spent:

152.25 + 654.50 = 806.75

Divide the total by pairs of shoes:

806.75/7 = $115.25

The answer is C. $115.25
