Question

1. Which expression is equivalent to the given expression? * -0.25 (84 – 32n) - n

a. 21 – 9n

b. -21 – 9n

c. - 21 + 8.25n

d. -21 + 7n

PLS HURRY​

Answer 1

Hi! Multiply -0.25 by the inner numbers.

-0.25 times 84 = 21
-0.25 times -32n = -8n

Then take the -n and add that
21 -8n - n

-8n - n (or -1n) = -9n

therefore, answer would be a) 21 - 9n
