Multiply (−4)(−2)(−5)

-4×-2=positive 8 then positive 8 times negative 5 equals negative 40

-40

Step-by-step explanation:

Parentheses mean to multiply so there for -4 times -2 gives you a positive 8, 8 times -5 gives you -40 simple as that

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)
