Answer:
105
Step-by-step explanation:
l is parallel m so angle 3+angle 6=180
(X+5)^2 = x^2 +10x + 25
the expression that is equivalent to
To multiply it we apply FOIL method
Multiply x with x+5 first and then we multiply 5 with x+5
If Y is 8, we solve by subtracting 8 on both sides,
0 = 6x
Divide by 6,
0 = x
x is equal to 0
A negative plus a positive equals a negative
