If it’s easy then why not do it yourself?
It goes largest exponent first, then go down until there’s no variable or exponent.
Answer is:
8x^5 + 7x^3 -x^2 +12x -2
First we take the number as it is. Second, we look at the last number. 6 is rounds up to ten which rounds the 3 up to a 4. So now we come up with 8.4, but that isn't a whole number. We can then round 4 to 0 because it's closer to 0 on a number line. Now, our answer is 8.0, but, in order to have a whole number, we can't have any decimals. we can, then, take away the 0 and the decimal, which leaves us 8, and 8 is a whole number; we can now say the answer is 8. :)
Answer:
n+1
If a pyramid has n number of sides
⇒number of vertices in the base = n
Since in a pyramid there is one vertex on the top,and n number of faces are on the sides,and one face is in the base.
Total number of faces of pyramid = n+1
