F(x) = 4 [cos (x)]^2 - 3 = 0
4[cos(x)]^2 = 3
cos(x) = √3 / 2
That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.
Answer: x = 30 degrees and x = 330 degrees
$126 / 6 = 21

Answer:
3 8/9
Step-by-step explanation:
How many times does 18 multiply to 70-
18 * 1 = 18
18 * 2 = 36
18 * 3 = 54
18 * 4 = 72
If we go past 3 times then it goes higher than 70, so 18 goes into 70 3 times.
18 * 3 = 54
70 - 54 = 16
The left over will be the numerator and the denominator stays the same.
Don’t forget to simplify-
16 / 2 = 8
18 / 2 = 9
