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.

A complete or whole circle is taken as 1 and parts of the circles are represented as fractions. For example, if a circle is divided into 8 equal parts, each of the parts represents the fraction 1/8. Three parts of such a circle would represent 3/8 and on.

Here we are dealing with a type of problems, where fractions representing certain parts in a circle are given and we are required to find the fraction representing the remaining unknown part of the circle. To solve such problems, we add up the fractions representing the fractional parts and then subtract the sum from 1, the whole circle. The result gives the fraction representing the unknown fractional part of the circle.
