Which expression is equivalent to 6 + 12x? A: 3(2 + 3x)
B: 18x
C: 2(2 + 6x)
D: 3(2 + 4x)

c

Step-by-step explanation:

D: 3(2+4x)

Step-by-step explanation:

Let's try to simplify each of the following expressions:

A- 3(2+3x) = 3(2)+3(3x) = 6+6x, which does not equal 6+12x.

B- 18x, can't be simplified further, and does not equal 6+12x.

C- 2(2+6x) = 2(2)+2(6x) = 4+12x, which does not equal 6+12x.

D- 3(2+4x) = 3(2)+3(4x) = 6+12x, which does equal 6+12x.

Let me know if this helps!

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

the answer is 99.
