Number 4 is C... 21
To complete the question, make the equation 5x + 15 + 3x - 3 = 180 because of supplementery angles.
Just solve for x to get 21.
Number 5 is C... 120
To complete this question, sub 21 in for X in the equation 3x - 3 to get 60. Subtract 60 from 180 to get 120.
Hi love! I believe it’s A. If not please report back. Thank you!
Answer:

Step-by-step explanation:
If a polynomial intersects the x-axis at (2,0) and (-2,0)
Then the zeroes are at x=2 and x=-2
(Outside of the question)
To find factors using the zeroes, we must have one side of the equation equal to zero.
x=2
x-2=0
factor (x-2)
x=-2
x+2=0
factor (x+2)
Answer:
No.
Step-by-step explanation:
The equation does not match the form of any conic section.
