Answer: 6m^2 +m -40
Step-by-step explanation: Distributing binomials calls for the FOIL method.
Multiply the First times the First: 3m×2m= 6m^2. (^2 means squared when we can't use superscript for exponents.)
Then multiply and combine the Outside and Inside terms: 2m ×8=16m. and -5 ×3m= -15m
16m - 15m = m
Then multiply the Last terms: -5×8= -40
You end up with
6m^2 + m -40
What you could do here is find a common denominator between 1/5 and 1/6 to find a fraction that doesn't have a denominator of 1/6.
In this case, the least common denominator is 30.
1/5 * 6/6 = 6/30
1/6 * 5/5 = 5/30
So, 5/30 is a fraction that refutes Maria's claim. Hope that helped!
Answer:
44 before she bought 7 more, 51 after she bought 7
42/24 = 42/24 or 7/4 = 42/24 so yes
