Answer:
5 and 1/6 for this problem so the one u have selected is right
<u>Answer-</u>
<em>The length of GE is </em><em>10 units.</em>
<u>Solution-</u>
Mid-Point Theorem-
The line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side.
As given,
EX = XF, so X is the mid point of EF
GY = YF, so Y is the mid point of GF
Hence, XY is the line segment connecting the midpoints of two sides of a triangle.
Applying the theorem,
GE = 2XY = 2×5 = 10 units

Answer:
x=1, y=10
Step-by-step explanation:
I'm gonna use the method of substitution.
2x+3(3x+7)=32
2x+9x+21=32
11x=11
x=1
y=10
