x = 0, 9
Step-by-step explanation:
To find our roots, set the binomial factors equal to zero:
x = 0
x - 9 = 0
x = 9
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
