Putting values

1)
2(3x-5)
Use the distributive property.
2(3x)+2(-5)
6x-10
That is not equal to 6x-8.
2)
2-2+5x
Simplify the like terms, 2 and -2
Add them together, 0
5x=5x the two expressions are equal
3)
2x+8 because there are x stickers in a pack
2(4+x)=2(4)+2(x)=8+2x=2x+8
Yes they are the same expressions.
The true statement about R ⊂ A is (a) yes, because all the elements of set A are in set R
<h3>How to determine the set operations?</h3>
The sets are given as:
U = {x | x is a real number}
A = {x | x is an odd integer}
R = {x | x = 3, 7, 11, 27}
From the given sets, we can see that the elements in set R are odd numbers
This means that the set R is a subset of set A
This is represented as:
R ⊂ A
Hence, the true statement about R ⊂ A is (a) yes, because all the elements of set A are in set R
