Prove that the sum of three consecutive exponents of the number 2 is divisible by 14.

So you want to prove . Notice that for , we have

If , we have

and we know , so will always be a multiple of 14 and we're done.

answer:

your answer is: c. 196 7/8 in^3.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
