Question

Which of the expressions are equivalent to the one below? Check all that apply.

5*(8 + 3)

A. 5*8 + 5*3
B. 5*24
C. 55
D. 43

Answer 1

5(8 + 3)

(5 * 8) + (5 * 3) <== this is one
5(11) = 55 <== this is one

Answer 2

Follow PEMDAS.

First solve the numbers inside the parenthesis

5(8 + 3) = 5(11)

Next, multiply 11 and 5

5(11) = 55

C. 55 is one of your answers

Another way of solving this is distributing 5 to all terms within the parenthesis

5(8 + 3)

5(8) = 40

5(3) = 15

40 + 15 = 55

A. 5*8 + 5*3 is another answer

hope this helps
