Answer:
x = -2,0,2
Step-by-step explanation:
9x^3 - 36x = 0
Factor out 9x
9x(x^2 -4) =0
Factor inside the parentheses, which is the difference of squares
(a^2 -b^2 = (a-b)(a+b)
9x (x-2)(x+2) = 0
Using the zero product property
9x =0 x-2=0 x+2 =0
x=0 x=2 x=-2
x = -2,0,2
Answer:
42 degrees & 138 degrees.
Step-by-step explanation:
By definition, "SUPPLEMENTARY ANGLES ADD UP TO 180 DEGREES."
That being said you can solve for the missing angle (or really just subtract 138 from 180).
180-138 = 42
