Answer:
- 8
Step-by-step explanation:
8( - 4 + 3)
- 32 + 24
- 8
group the 1st 2 terms and last 2 terms:
(Z63 -2z^2) + (9z-18)
factor out GCF:
z^2(z-2) + 9(z-2)
now factor the polynomial:
(z-2) (z^2+9)
They are supplementary angles. They are located on a straight line, and when added together they will add up to 180 degrees.
Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
