A) Sub g(x) and h(x) into the equation:
x^2 + 3x - 40 - (-x -3)
= x^2 + 3x - 40 +x + 3
= x^2 + 4x - 37
Find x:
x= 4.40 and x= -8.40
b) Sub f(x) and g(x) into the equation:
(x^2 - 64) / (x^2 + 3x -40)
= ((x+8) x (x-8)) / ((x+8) x (x-5))
= (x - 8) / (x-5)
Find x:
x= 8 and x = 5
How to get those number:
(x^2 - 64) = x^2 - 8^2 = (x-8) x (x+8)
( x^2 + 3x - 40) = (x^2 + +8x - 5x - 40) = x( x + 8) - 5( x + 8) = (x-5) x (x+8)

B. Is the correct answer. A circle can not form a perpendicular bisector as it is rounded and not straight.
Answer:
8, 82
Step-by-step explanation:
Let x = angle measure
y = complement
y = x+74
Complements add to 90
x+y = 90
Substitute y = x+74 into the equation
x+ x+74 = 90
Combine like terms
2x+74 = 90
Subtract 74 from each side
2x+74-74 = 90-74
2x = 16
Divide by 2
2x/2 = 16/2
x=8
The first angle is 8
8+74 = 82
The other angle is 82
