Help pls and thank you

Answer 1

Answer:

The First option, b(4*3) is correct

The Second option, 3(3b+b) is correct

The Fourth option, 4b(3) is correct

Step-by-step explanation:

To find what other expressions are equal, all we do is find what the original is equal to and the options are as well.

To find the value of 3(4b) all we do is distibute the 3 into 4b. We do this by multiplying.

3 * 4b = 12b

Now that we know what the original is equal to, we must find what the options are equal to:

1.

b(4 * 3)

4 times 3 is 12.

b times 12 is 12b.

12b is 12b meaning the first option,  b(4 * 3) is correct.

2.

3(3b + b)

3b plus b would be 4b.

3 times 4b is 12b.

12b is 12b meaning the second option, 3(3b + b) is correct.

3.

4b + 3

Nothing further can be done to this since 4b and 3 can't become one variable.

4b + 3 is not 12b meaning the third option, 4b + 3 is not correct

4.

4b(3)

4b times 3 is 12b

12b is 12b meaning the fourth option, 4b(3) is correct
