The answer is C. 3(y + z)
Proof:
y + y + y + 3z
Add same terms:
3y + 3z
Factor out 3:
3(y + z)

Answer:
12.5 inches
Step-by-step explanation:
Given the equation for the cross section of a parabolic satellite TV dish:
y=1/50x^2
Equation of a parabola :
(y - k) = 1/4p * (x - h)^2
Distance of the focus from the Vertex = p
Comparing both equations :
1/4p * (x - h)^2 = 1/50 * x^2
4p = 50
Divide both sides by 4
4p/4 = 50/4
p = 12.5 inches
