Explain why the question -2(3x+6)=6(x+2)

x = -2

Step-by-step explanation:

So here we are to calculate the value of x.

Distribute;

-6x - 12 = 6x + 12

Subtract 6x from both sides

-12x - 12 = 12

Add 12 to both sides;

-12x = 24

Divide both sides by -12

x = -2

14

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
