Answer:
x = −4 and x = 4
Step-by-step explanation:
4x² = 64
Lets get x² on its own. To do this we divide each sides by 4:
x² = 16
Now to get just x, we need to square root this answer:
√x² = √16
x = √16
x = 4
But this can be ±4 as it -4 and 4 squared both give 16.
So your answer is x = −4 and x = 4

3x can be factored into 3 times x. The numerical factor is 3.
1/x = x^-1
sqrt(x) = x^(1\2)
Therefore, answer is:
x^(-1/2)
sin(30°) = 4/x. Multiply both sides by x.
x * sin(30°) = 4. Divide each side by sin(30°).
x = 4/sin(30°). Solve for x.
x = 8.
Area of cone = 1/3 base area x height
Area of cone = 1/3 (16π) x 9
Area of cone = 48π ft³ or 150.8 ft³
