Answers

Answer 1
Answer:

Too Confusing !!

but I think it's

g(x)=(x^2+4x-12)(x-3)

=(x+6)(x-2)(x-3)

=x+6 = 0

-6 -6

x=-6

x-2 = 0

+2 +2

x=2

x-3 = 0

+3 +3

x=3

The zeros are {-6, 2, 3}

hope this helps ! :)

Two angles with measures (6x + 60) and (90) are supplementary. What is the value of x?

Answers

Supplementary angles add up to 180, so 
6x+60+90 = 180 and solve for x
6x= 30
x=5
supplementary means that the angles add to 180, so solve the equation 6x+60+90=180. 6x=30 x=5
