Can someone solve this?

1) A and D

2) C and D

3) Angle Y > Angle Z

4) OM, ON, MN

5) least: 7 cm, greatest: 23 cm

Step-by-step explanation:

1) angle C > Angle A > Angle B

If the lenth is greater, angle opposite is greater

2) If the lenth is greater, angle opposite is greater

3) XY is opposite angle Z

XZ is opposite angle Y

XZ > XY,

So Angle Y > Angle Z

4) Angle O = 180-54-61 = 65

5) 15 - 8.5 < third side < 15 + 8.5

6.5 < third side < 23.5

Least: 7

Greatest: 23

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
