Hello from MrBillDoesMath!
Answer:
Choice A
Discussion:
As the lines are parallel, corresponding angles are equal. This means that
angle x (just to the left of the letter a) and its corresponding angle ( just above line b -- above the the "2x" value shown) are equal..
In other words,
x = 180 -2x
as there is 180 degrees in a straight line.
Add 2x to both sides of the equation:
x + 2x = 180 - 2x + 2x =>
3x = 180 =>
x = 60

Answer:
- , 0
Step-by-step explanation:
8x⁴ + x = 0
factor out x:
x(8x³ + 1) = 0
The zero product property says that one of the terms needs to be equal to 0:
x = 0
8x³ + 1 = 0
Solve for x in the 2nd equation:
8x³ = -1
x³ = -
x = -
When x is either 0 or - , the product will be equal to zero.
The roots are 0 and -
