Answer: See below
Step-by-step explanation:
a) 6(3x+4y-8)
Use the distributive property:
6*3x + 6*4y - 6*8
18x + 24y - 48
So D is the correct answer
b) Factor out 4 because it can fit into 12 - 3 times - and 4 - one time.
12+4x
= 4(3+x)
So D is the correct answer
c) When you expand both C and D and simplify, you get 16x+36 as solution
d) 14x+2y+10z
Factor out 2 because it can fit into 14, 7 times. 2, one time. And 10, 5 times
14x+2y+10z
= 2(7x+y+5z)
So D is the correct answer again ;)
