Answer:
-16
Step-by-step explanation:
So let’s solve for 7x. So 7x=34. So 7x-50 is 34-50 or -16

If the diameter of the cylinder's base is 10, then the radius is half that, or 5.
Answer:
see explanation
Step-by-step explanation:
Given
- 
[ - 
c + 6c + 1 ] - 3c
Distribute the square bracket by -
= 
c - 3c - - 3c ← combine like terms
= c - 6c -
= c - 
c -
= - 
c -
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
