k and m must satisfy 8k = 1 mean k = ⅛
and 2km+⅝=0 mean m = -5/2
The correct answer will be -4x - 10 which is A. X subtracts to the other side and makes it -4x, then 6 +-4 = -10
Answer:
1. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
