What is the answer to question 12?

x = 10

Step-by-step explanation:

30 - x/ 10= 2

10 ( 30 -x)/10 = 2 * 10

30 - x = 20 Simplify

Subtract 30 from both sides

30 - x - 30 = 20 - 30

Simplify - x = - 10 the divide both sides by -1

x = 10

Good luck

the answer is 99.

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)
