Find the greatest common factor (GCF)

45x²y

Step-by-step explanation:

Find the gcf of 9 and 15. Which is 45

then the most amount of X and Y which is x² and y

A

Step-by-step explanation:

The GCF, or greatest common factor, is the number of which both numbers can be multiplied to equal the number.

The highest number that divides exactly into two or more numbers.

It is the "greatest" thing for simplifying fractions!

Let's first take the numbers, 9 and 15.  Ignore the other stuff for now.

The GCF for 9 and 15 is 45 because both 9 and 15 can be multiplied to get it.  Plus, 45 is the lowest number of which it can work with 9 and 15.

Now let's bring back the other stuff.

x³y+x²y²

Let's combine like terms.  x³+x²= x⁵ because the powers 3 and 2 combine to be 5.  

Same with y.  y+y²= y³ because y is y to the power of 1.  The power of 1 plus the power of 2 equals the power of 3.

We have x⁵ and y³.  Now take the 45 from before and add the x⁵ and y³.

We get 45x⁵y³, which is choice A.  :)

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
