Question

Mark which expressions are equivalent to 8 –2(5x –3). Explain or show work to justify your decision.

HELLLLLLLLLLp

Answer 1

Explanation: Equivalent:

6 x 5x, 6 x -3 30x - 18

Combine like terms, (8 + 6) (10x) 10x - 14

8 - (-6) (10x) 10x - 14

8 -(-6) (-10x) -10x - 14

(2 x -5x = -10x) (2 x 7 = 14) 2(-5x + 7)
