Answer:
102a
Step-by-step explanation:
The first step is to subtract 65 from 89. PEMDAS states that equations in parentheses should be evaluated first.
89 - 65 = 34
Therefore, the equation becomes
3a(34)
Now, multiply 3 by 34, then multiply that by a.
3 * 34 = 102
102 * a = 102a
So, the final answer is 102a.
