Answer: The answer is A : 6x^2+24x+24
Step-by-step explanation:
(2x+4)(3x+6)
multiple the two equations together
2x*3x=6x^2
2x*6=12x
4*3x=12x
4*6=24
combine like terms
6x^2+12x+12x+24
6x^2+24x+24
Answer: 12a=48
Step-by-step explanation:
4a+6b=10
4a=10-6b
a=(10-6b)/4
a=(5-3b)/2
2a-4b=12
2((5-3b)/2)-4b=12
(5-3b)-4b=12
5-7b=12
-7b=7
b=-1
2a-4b=12
2a-4(-1)=12
2a+4=12
2a=8
a=4
a=4, b=-1
12a=48
It's out of D or A I can't really see
Answer:
k = 3
Step-by-step explanation:
5(ky-6)=15y-30
Factor out a 5 from the right side
5(ky-6)=5(3y-6)
Divide each side by 5
ky -6 = 3y -6
Add 6 to each side
ky = 3y
divide by y
k = 3
