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
The second one !!!
I’m pretty sure
Answer:
12
Step-by-step explanation:
(69.50-12.50) divided by 4.75 is 12
The 30 units line is the midpoint of the two sides it’s joining(as it cuts both as 21,21 and 44,44)
Therefore we can use midpoint theorem to say that x = 60 ( the line joining the midpoints of two lines is parallel and half of the third line in a triangle)
