Answer:
5
Step-by-step explanation:
0.5x=6-3.5
0.5x=2.5
x=2.5÷0.5
x=5
Answer:5
Collect like term:
6-3.5=0.5x
2.5=0.5x
Divide both side by 0.5
Ans:5
Therefore x=5
I'm not sure but I think it is C.

Factor theorem: .
Synthetic division: .
By the factor theorem, a monomial of the form (where is a constant) is a factor of polynomial if and only if .
In this question, the monomial is , which is equivalently . .
.
Hence, by the factor theorem, , which is equivalent to , is a factor of .
The remainder is when dividing by . Hence, is a factor of .
