The Distributive Property is an instance such as this:
a(x+y), where you multiply a and x, and a and y, and add those two values together.
For example:
a(x+y) = ax + ay, since we multiplied a and x together and a and y together and added the remaining values.
Another example:
2(4+x) = (2 x 4) + 2x = 8 + 2x, since we multiplied 2 and 4 together and 2 and x together and added the remaining values.
Here we have 6+4(3x-2)+5.
There is only one set of parentheses where we can use the distributive property.
Distribute 4(3x-2).
We multiply 4 and 3x together, and multiply 4 and -2 together, and add up the remaining two values.
4(3x-2)=12x-8
Substitute 12x-8 for 4(3x-2).
6+12x-8+5
12x+6-8+5
12x+11-8
12x+3
Your answer is Choice B, 12x+3.
