So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:
8x+10=90
Then you subtract 10 on both sides of the problem to get:
8x=80
And then divide 8 on both sides to get
x=10
In order to factor a polynomial, you have to find its roots

So that you can factor it as

So, in this case, we're looking for the solutions of

So, the polynomial can be written as

C) 3.07 x 10 to the negative 4
Divide 132 by 16 to get 8.25 and you have to round up because you can’t fit 0.25 of people on a table.
