x = 47.8

y = 71.5 - 47.8

71.5 - 47.8 = 23.7

The base of a pyramid has n sides. write an expression for the number of corners on the pyramid.

melisa1 [442]

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

Find the complete factored form of the polynomial -24a6b4-40a3

Naddik [55]

For this case we have the following polynomial:

$-24a ^ 6b ^ 4-40a ^ 3$

We must find the greatest common factor of the terms of the polynomial.

The GCF of the coefficients is given by:

$24 = 3 * 8\\40 = 5 * 8$

Then we look for the GFC of the variables:

We have then:

$a ^ 6 = a ^ 3a ^ 3\\a ^ 3 = a ^ 3$

Finally rewriting we have: $-24a ^ 6b ^ 4-40a ^ 3 = -8a ^ 3 (3a ^ 3b ^ 4 + 5)$

Answer:

the complete factored form of the polynomial is:

$-8a ^ 3 (3a ^ 3b ^ 4 + 5)$
