I remember doing this one and its c
We can use quadratic formula to determine the roots of the given quadratic equation.
The quadratic formula is:

b = coefficient of x term = 5
a = coefficient of squared term = 1
c = constant term = 7
Using the values, we get:
So, the correct answer to this question are option E and F
The formula for volume of a sphere is V=4/3πr^3.
If we substitute 18 in for "r", we can work the problem out from there.
V = 4/3(3.14)(18)^3
V = 24,416.64 cubic units, so your answer will be C.
Hope that helps!

Please let me know if you want me to add an explanation as to why this is the answer/how I got this answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
Step-by-step explanation:
the triangles are similar, also is a right triangle
therefore
16/8=10/x
x=(8*10)/16=5
x=5
