Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3

Answer:
To find the perimeter, you actually need to find the circumference of a circle.
Step-by-step explanation:
The formula to find the circumference is:
C= 2 pi times r
The r is the radius of the circle. The 2 stays the same. If you have the radius then you are fine.
E.g. If you have a circle and you're given that the radius the distance from the center to a point on the circle is 10. Since you have the radius, all you will have to do is C= 2 pi times (10). So 2 times 10 is 20 so it'll be 20 pi for the circumference.
I hope this helped sorry if it's confusing. If you have any questions please ask.
A1=12, a2=27, a3=42, etc. The pattern is that you’re always adding 15 after starting with 12. So the general rule is...
an=12+15(n-1)
So then...
a18=12+15(18-1)
a18=12+15(17)
a18=267
