Hope this helped my dude.
Answer:
(x+10) and (x-6)
Step-by-step explanation:

Answer:
V = 3538.78
Step-by-step explanation:
V = r²hπ
r= radius (7)
h = height (23)
π = pi (3.14)
V = (7^2)(23)(3.14)
V = 3538.78
Yes it would be 7.1 is greater than 7
14 2/5 as a decimal is 14.4
3/8 as a decimal is 0.375
14.4 ÷ 0.375 = 38.4 or 38 2/5
