A semicolon is used to separate variables from parameters. that we are defining a function of the parameters that returns a function of the variables.
"Bisect" is a mathematical term which means to divide into two equal parts. We can bisect angles, lines, and more. The line that divides is called the "bisector".
sample problem:
<span>
If Ray QS bisects angle PQR , m of angle PQS=7x-6 and m
of angle SQR =4x+15,find m of angle PQT.
Since it is mentioned that ray QS bisects the angle PQR, it is understood that the m of angle of PQT is </span><span><span>4x+15. It is because as metioned earlier, to bisect angles or lines, it means dividing into 2 equal parts, thus, bisect equal measurements of angles.

4a+6b is the answer you have to look at the variable so for a 4a-2a+2a and b there is just one variable so it’s 6
