HELLLLLLLLLLp

Answer 1

Answer:

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)
