Answer:
The answer is 65
Step-by-step explanation:
Evaluate:
8x + 9
When x = 7
Use PEMDAS order of operations:
8x + 9
= 8(7) + 9
= 56 + 9
= 65

Answer:
3b²+ 4b² + 4b + 2b + 1 +2
7b² + 6b + 3
Answer:
12
Step-by-step explanation:
Volume of cylinder is pi*r^2*h (this is equal to 540pi in this case)
So we have 540pi=pi*r^2*h
this means that 540=r^2*h (I just divided both sides by pi since both sides were being multiplied by pi)
The height,h, is 15 so plug in 540=r^2*15
Divide both sides by 15 giving 540/15=r^2
So r^2=36
So r=6
The diameter,d, is twice the radius, r.
So d=2(6)=12

Answer: 
Step-by-step explanation:
Given the following inequality:
You need to solve for "x" in order to find the solution.
The steps are:
1. Add 
to both sides of the inequality:
2. Add 
to both sides:
3. Divide both sides by 
:
Notice that "x" is less than 8. This indicates that 8 is not included in the solution and you must use parentheses.
The solution in Interval notation is:
