Geometry Question plz help
posted by Chrissy on .
Could someone please explain how to figure this out step by step. I'll give you one of my problems and I'll try to figure out the rest.
Directions: For each situation find the value of x and the measure of the indicated segment.
1. UY=4x3, YV=x; UV

If UY and YV are segments of a straight line, then
UY+YV=UV
4x3+x=UV
If one knows UV, then one can solve for x. 
Do I add 4x+x which equals 5x so would it be 5x3=UV??

could you check the one i did myself
2. UV=x+6,UY=x1;YV
UY+UY=YV
x+61=YV
Answer: x5=YV 
well, since UV is greater then UY, it means that UV is the longer segment, UY one part of it, and YV the other part.
So UY+YV=UV
then proceed. 
So would the answer be x^2+YV=7
