Answer:
D
Step-by-step explanation:
I’ll assume the question is asking us to factor the above polynomial:
5x^2 + 10x - 45
Factor out a 5:
5(x^2 + 2x - 9)
This appears to be an irreducible quadratic polynomial, so let’s leave it alone.
5x^2 + 10x - 45 = 5(x^2 + 2x - 9)
One solution.
-20 divided by 5 is equal to -4. Unless both sides have the same number or one side has -=0 then it’s one solution
Answer:
125
Step-by-step explanation:
6 and 7 are on a straight line (180 degrees)
Angle 2 is equal to Angle 6
Therefore 180 - Angle 6 = Angle 7
180 - 55 = 125
Phoebe is correct. The line on the graph would be vertical in the x-axis value of 12.
