The answer would be c because it means Multiply and whenever a variable is next to a number in this case 39s then that means it a multiplication
So C. 39s
X=7
(15x+3)=108
x=7
if you plug 7 in for x
(15(7)+3) it equals 108
Use Order of Operations!! Remember PEMDAS!
P: Parentheses first
E: Exponents (ie Powers and Square Roots, etc.)
MD: Multiplication and Division (left-to-right)
AS: Addition and Subtraction (left-to-right)
7+25•4 (multiply 25 by 4 first)
7+100 (then add 7 to 100)
107
So your final answer would be 107
Hope this helped and I hope you have an awesome day!! :D
