It looks like only A and B, but could be trick question?
Answer:
<h2>One of them i believe is 2 (3+4m) and another one is 6+8m</h2>
Step-by-step explanation: so for the first one you have your equation 18+4(m-3)+4m you take the second part and do 2(9+2(m-3)+2m) then after that you get 2(9+2m-6+2m) and you get you first answer 2(3+4m)
Your second probelm 6+8m you have your equation 18+4(m-3)+4m you do 18+4m-12+4 and you subtract all th likes terms so you get 6+8m
Hope this helps!
Answer:
The basic answer to your question is that we have to start somewhere.
The essence of mathematics (in the sense the Greeks introduced to the
world) is to take a small set of fundamental "facts," called
postulates or axioms, and build up from them a full understanding of
the objects you are dealing with (whether numbers, shapes, or
something else entirely) using only logical reasoning such that if
anyone accepts the postulates, then they must agree with you on the
rest.
It can sometimes be proven.
Answer:
C
Step-by-step explanation:
2.2-2.5
Since a + and a - make a minus if we have 2.2+(-2.5) we would get 2.2-2.5. So C is the anwser.
Step 2 a negative times a positive is a negative so the answer is -75.6
