Answer: 31 & 42
<u>Step-by-step explanation:</u>
1st #: x
2nd #: x + 11
1st# + 2nd# = sum
x + x + 11 = 73
2x + 11 = 73
2x = 62
x = 31
2nd #: x + 11 = 31 + 11 = 42
See attachment for one such shell. The volume is given by the sum of infinitely many thin shells like this, each with radius

and height determined by the vertical distance between the upper blue curve and the lower orange curve for any given

, i.e.

.
The volume is then
20 is the answer to the question you asked.
Answer:
2 + m- 1 + m
Step-by-step explanation:
3m +1 -m
Combine like terms
3m-m +1
2m +1
We can split the m's
m+m +1
And we can rewrite 1 as 2-1
m+m+2-1
m+2+m-1
Rearranging the order
Answer:
LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18
Step-by-step explanation:
9 = 32
-1 = -1
-1 = -1
+2 = 2
+2 = 2
+2 = 2
LCM = 2×3^2 = 18
18 / 9 = 2
18 / -1 = -18
18 / -1 = -18
18 / +2 = 9
18 / +2 = 9
18 / +2 = 9
