Answer:
The correct option is A.
Step-by-step explanation:
If the degree and variables of two terms are same, then they are called like terms.
In option A.
The given expression is
Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.
By combining like terms we get
In options B, C and D, there are no like terms, So only the expression

Answer:
17x-15 ................... I needed to put dots so I can have 20 characters
(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
