15m + 2n, first you have to pair the matching variables, 8m and 7m along with the sign in front of them. so 8m(+7m), you would then add those then do the same with the other, +4n(postive) and -2n, so subtract 2 from 4 and get 2. put them together and it’s 15m+2
Let A (1, 3, 5, 7}, B (5, 6, 7, 8}, C (5, 8} D {2, 5, 8}, and U 1, 2, 3, 4, 5, 6, 7, 8}. Determine whether the statement shown b

Answer:
True
Step-by-step explanation:
Given are some sets A, B, C, D and Universal set U.
We have

When we change the order of elements of A in any manner also the set A' thus obtained will be equal to A only
Hence here A' =
=A
This is because whenever we take any element x in A this belongs to A'
Hence 
Similarly any element y in A' also belongs to A
So A⊂A'
Together we have
Option d true
Algebra cab act as a tool to improve communication by showing specific patterns and possible connections.
<h3>How to illustrate the information?</h3>
Algebra is a symbol that's used to represent mathematical connections. It's a tool that people may and do use to model and answer questions about real-life scenarios.
It should be noted that much of arithmetic operations are typically given out using algebra, as this is a language of specific patterns and possible connections.
It is also a means of working with abstract notions and then applying them, which frequently leads to the formation of generalizations and insights outside of the original context.

There is a 1/2 chance that he will get at least one of the two features.
There are 3 x 4 = 12 possibilities. There are all 4 colors of each 3 sizes.
All 4 of the medium trucks have one of the features.
For the other 2 sizes, only the red truck will have one of the features.
There are 4 + 2 = 6 possibilities out of 12 for a chance of 6/12 or 1/2.
