Answer:
false buddy that is the answer
C) x+3
first one factors to (x+3)(x-3)
second factors to (x+3)(x-2)
1/3 + 5/6 + 5/12

125 = 5^3 = 25 * 5

The simplification you are trying to do involves finding the prime factorization of a number. Since 125 is not divisible by 2, move on to 3. 125 is also not divisible by 3, so move on to 5. Then 125/5 = 25, and 25/5 = 5, so 125 = 5^3. The prime factorization of 125 is 5^3.
15 dozen = 180 cookies
180 ÷ 24 = 7.5
7.5 x 2.5 = 18 3/4 cups of flour
