Evaluate

5 x (4 + 4) + 2

42

Step-by-step explanation:

Start with (4+4) which equals 8

Multiply 8 by 5 then add 2

42

Step-by-step explanation:

First you add what is in the parentasis so 4+4=8 Then multiply 8x5=40 So 40+2=42

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)
