Answer:
A) x = ±2i√3
Step-by-step explanation:
We presume you want to find x such that f(x) = 0.
Divide by 13:
x² + 12 = 0
Subtract 12:
x² = -12
Take the square root:
x = ±i√12 = ±2i√3
It is located in Wisconsin, I don't know the second question
Answer:
corresponding angles
the angles are equal
equation: 9x+8 = 4x+18
x=2
angle measurements: 26⁰
Step-by-step explanation:
solve your equation
9x+8 = 4x+18
subtract 4x from each side
5x + 8 = 18
subtract 8 from each side
5x = 10
divide by 5
x = 2
insert x=2 into original equations to make sure you get the same answer.
9(2) + 8 = 26
4(2) + 18 = 26
