How can you express the properties of operations to evaluate this expression 18 + 4(28)

Akimi4 [234]

Answer:

I don't know if I'm understanding your question correctly. But I'll try...

In this problem you need to remember PEMDAS!

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

18 + 4(28) -First you would multiply 4 by 28 since the 28 is in parentheses.

18 + 112 -Now you would add to find your answer

= 130

I hope this helps!
