Answer:

A. 48r² - 10r + 3

Step-by-step explanation:

-48r² - 18r + 8r + 3

2. <u>Combine like terms</u> (-18r and 8r):

-48r² - 10r + 3

So, your answer is -48r² - 10r + 3

Plz help this should be easy and I will give brailiest
oee [108]

Answer:

Step-by-step explanation:

x - represents 1 point shots

(54 - x) - represents 2 point shots

x + 2(54 - x) = 89

x + 108 - 2x = 89

-x + 108 = 89

x = 19 (1 point shots)

54-x = 35 ( 2 point shots)

Test:

19 + 35 = 54 (total shots)

19 x 1 = 19

35 x 2 = 70

70 + 19 = 89 points
