5(-3x-7) (first multiply 5 to -3x then to -7)
-15x-35.
The answer is D) -15x-35
We have a formula for that( according to the Intersecting chords theorem)

3×4=2×jk
6=jk
If by base of 10, you mean that the diameter of the base is 10, then the radius of the base is 5.
volume = pi * r^2 * h
volume = pi * 5^2 * 10
volume = 250pi, or approximately 785
Your answer is 26,453
Although I don't feel as if this is a homework question, I will still show the work.
Work:
Step 1: 999 + 999 = 1,998
Step 2: 1,998 + 999 = 2,997
Step 3: 2,997 + 23,456 = 26,453
Hope I was able to help! :)
