Expand if necessary, combine like terms (x+2) (x+2)

x^2 + 4x + 4

Step-by-step explanation:

x^2 + 4x + 4

Step-by-step explanation:

We can do this first

(x + 2)^2

Then we can use our knowledge and do

x^2 +4.

We have to multiple the two by two and then x because that is a rule in

(a + b) ^2

=

a^2 + b^2 + 2ba

So we end up with x^2 + 4x +4

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
