Answer:
18+316−251−11
=72
Step-by-step explanation:
18+316−251−11
=334−251−11
=83−11
=72
For this case we have the following polynomial:

We must find the greatest common factor of the terms of the polynomial.
The GCF of the coefficients is given by:

Then we look for the GFC of the variables:
We have then:

Finally rewriting we have:

Answer:
the complete factored form of the polynomial is:

The square root of 25 is 5, so each side is 5metres x
The answer i believe is C
Answer:
62390
Step-by-step explanation:
you have to round up if it's 5 or more and round down if it's less.
