Answer:
wheres the picture?
Step-by-step explanation:
5y4(2y5) = 10y9 CORRECT
5x3(6x4) = 30x7 CORRECT
3b3(-2b4) = 6b12 INCORRECT
4c4(3c2) = 12c8 INCORRECT
When you are looking for this, the best way to do this is to divide 28 by 7. This will give you 4.
The other way to do this is to list the factors of 28, which are 1,2,4,7,14,28, and you will then be able to see which two are paired.
In this case, x is 4.
