What is x? −4(3x+1)+x−3=15

Step-by-step explanation:

So

-4 * 3x = -12x

-4*1 = -4

Equation: -12x + -4 + x -3 = 15

move -12x and x to the other side, and 15 to the other/

Equation: -4+ (-3)-15 = 12x - x

simplified: -22=11x

x= -22 divided by 11

x= -2

x = -2

Step-by-step explanation:

-4(3x +1) = -12x - 4

-12x - 4 + x - 3 = 15

       +4              +4

-12x + x - 3 = 19

-11x - 3 = 19

      +3    +3

-11x = 22

22 / -11 = -2

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
