Answer:
30
Step-by-step explanation:
By following PEMDAS
P - parenthesis | E - exponent | M - multiply | D - divide | A - add | S - subtract
You first work out what is in the parenthesis first. The order of operation would first have you multiply 4×4 = 16, next you will add 4 and subtract 5... 4-16+5 = 15. Finally multiply to what's outside the parenthesis (15)×2. And that's how you arrive to 30 as the final answer.
