Point J is on line segment \overline{IK} IK

. Given JK=2x, JK=2x, IJ=5x, IJ=5x, and IK=x+6,IK=x+6, determine the numerical length of \overline{JK}.

JK

.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
