We know that the volume of a rectangular prism is length*width*height. So for part a, we just need to multiply those values.
A:
So, the answer to part A is
10(2x³-x²)
For part B, all we do is plug 2 in for x into our polynomial.
So, the volume is 120 cubic units.
Hope this helps!
Answer:
3/9
Step-by-step explanation:
numerator:7-4=3/9
5^2 = 25
13^2 = 169
169 - 25 = 144
The square root of 144 = 12.
12 + 2 = 14.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169
-25 -25
b^2 = 144
sqrt sqrt
b = 12
+2
14
I think it's false.... 5/6 is 83.33% as a percent so I don't think it's true.
