Correct it is right u have to multipl
Answer:
1) V = 12 π ㏑ 3
2) 
Step-by-step explanation:
Given that:
the graphs of the equations about each given line is:

Using Shell method to determine the required volume,
where;
shell radius = x; &
height of the shell = 
∴
Volume V = 



V = 12 π ( ㏑ 3 - ㏑ 1)
V = 12 π ( ㏑ 3 - 0)
V = 12 π ㏑ 3
2) Find the line y=6
Using the disk method here;
where,
Inner radius 
outer radius R(x) = 6
Thus, the volume of the solid is as follows:





Recall that:

Then:





The graph of equation for 1 and 2 is also attached in the file below.
Answer:
20
Step-by-step explanation:
Let Bonnie's age = b.
Clyde's age is 8 year more than Bonnie's age, so Clyde's age is
3b + 8
The product of the ages is 80, so
b(3b + 8) = 80
3b^2 + 8b = 80
3b^2 + 8b - 80 = 0
(3b + 20)(b - 4) = 0
3b + 20 = 0 or b - 4 = 0
3b = -20 or b = 4
b = -20/3 or b = 4
Discard the negative answer since an age is not a negative number.
Bonnie's age is 4.
Clyde's age is 3 * 4 + 8 = 12 + 8 = 20.
Answer: Clyde's age is 20.
Answer:
7x-5
Step-by-step explanation:
x-5(5x-1) becomes 6x-5+1x-5. Once you simplify that, you get 7x-5.
