U have to have the same denominator and then add or subtract but you can never subtract the denominator or add it

First of all you need to make sure the denominator is the same. It would make it easier from there. :)

What is -3(4r - 8) = -36

sweet [91]

-3(4r - 8) = -36

Mutiply the bracket by -3

(-3)(4r)(-3)(-8)= -12r+24

-12r+24= -36

move +24 to the other side

sign changes from +24 to -24

-12r+24-24= -36-24

-12r= -60

divide by -12

-12r/-12= -60/-12

r= 5

Answer: r= 5

11) If A = {19, 20, 21, 24} and B = {17, 19, 20, 22), list the elements of A U B.

Elodia [21]

Answer:

A U B = {17, 19, 20, 21, 22, 24}

Step-by-step explanation:

The symbol U is the union symbol, which denotes the union of two sets.

This means that given two sets A and B, the expression

A U B

indicates all the elements that belong to either set A or set B.

In this problem, we have the following two sets:

A = {19, 20, 21, 24}

B = {17, 19, 20, 22}

We can therefore list all the elements belonging to either set A or set B, they are:

17, 19, 20, 21, 22, 24

So, the expression A U B indicates the set:

A U B = {17, 19, 20, 21, 22, 24}
