What is the simplified expression for the expression below
4(3x-2)+ 6x(2-1)

18x - 8

Step-by-step explanation:

First, distribute the 4 to the first set of parentheses:

4(3x - 2) + 6x(2 - 1)

12x - 8 + 6x(2 - 1)

Then, simplify the second set of parentheses:

12x - 8 + 6x(1)

Simplify and add like terms:

12x - 8 + 6x

18x - 8 is the simplified expression

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

easy math just plug in a and b
