Choose Yes or No to tell whether the expressions are equivalent. 1. 4(5c + 3) and 9c + 7 yes or no 2. 10f – 10 and 2(8f – 5) yes

Juli2301 [7.4K]

Answer:

1) No

2) No

3)Yes

4)No

Step-by-step explanation:

Distributive property: a(b + c) =a*b + a*c

1) 4(5c + 3) = (4*5c) + 4*3

= 20c + 12

2) 2(8f - 5) = (2*8f) - (2*5)

= 16f - 10

3) 3(4g + 7) = (3*4g) + (3*7)

= 12g + 21

YES

4) 6(4j - 6) =(6 * 4j) - (6*6)

= 24j - 36
