Answer:
9(6+5x)
Explanation:
54 + 45x-------- (Write out the original equation in standard form. This has already been done.)
=9(6) + 9(5x) -------- (For this step, you rewrite 54 as 9(6) and 45 as 9(5).
=9(6+5x)--------- (For this step, you factor out 9 because it is the greatest common denominator.)
