Which of the expressions are equivalent to the one below? Check all that apply.
2 answers:
5(8 + 3)
(5 * 8) + (5 * 3) <== this is one
5(11) = 55 <== this is one
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
