125

Step-by-step explanation:

( 3x - 70 ) is exterior angle.

60 and x are interior angles.

Formula : -

Exterior angle of a triangle

= Sum of two interior angles in a triangle

3x - 70 = x + 60

3x - x = 60 + 70

2x = 130

x = 130 / 2

x = 65

m∠LKM = 3x - 70

= 3 ( 65 ) - 70

= 195 - 70

m∠LKM = 125

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
