Answer:
pretty sure its A?
Step-by-step explanation:
EDGE 2020
Answer: 3x(9x^2+1) or C on edge
B looks the most reasonable
one solution : x = -1
look this solution :
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
-3x + 2.4 = 19.2
v <u>-2.4</u> <u>-2.4</u>
v 0 16.8
<u>-3x</u>=<u>16.8</u>
-3 -3
x=-5.6
hope this helps,
b
is the proper answer
