Question

Can you help me simplify this and explain it ---------------------------------------------------------------------------------------------------------------------------------------------------------------------





28 + 7g ; distributive

(12r + 15) – 65 ; associative

24 – (8p – 12) ; distributive

Answer 1

A. Factor 28 + 7g  7(g + 4) 

add 
28 + 7g 

= 7 (g + 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36
