1. Evaluate the following:

PLEASE HELP ITS DUE AT 4

= 7

- = -10

10 + = 23

Step-by-step explanation:

a/b. Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

c. Simplify each radical, then combine.

hope this helps! Can i get brainliest? please :)

answer: x=3 and y=4

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)
