The answer is 30.
if 7=a and 2(a+8)
all you need to do is replace a with 7
so the formula would then be 2(7+8)
next you would solve in the parentheses.
2(15)
and 2(15) is the same as 2 x 15
so the answer would be 30
Answer: E. 30
Step-by-step explanation:
Cause a=7 and the equation is 2 (a+8) and it the same as 2 × (7+8) which if you use PEMDAS it's 2 × 15 =30
