Answer:
The GCF of 175 and 280 is 35.
We are given two binomials: x+4 , x^2-9.
x+4 can't be factored. Therefore, it is a prime.
Let us work on x^2-9.
9 could be written as 3^2.
Therefore, x^2-9 = x^2 - 3^2.
Now, we can apply difference of the squares formula to factor it.
We know a^2 -b^2 = (a-b) (a+b).
Therefore, x^2 - 3^2 can be factored as (x-3) (x+3).
So, x^2-9 is not a prime binomial because it can be factored as (x-3) (x+3).

The text of this expression is:
"If 3 is added to twice a number, the result is 17. Find the number"
Let's call
the number we want to find.
Twice the number is equal to

So, if we add 3 to 2x, we get

And we know that this is equal to 17:

Now we can solve the equation to find x: first, we subtract 3 from both sides

Now we divide both sides by 2:
