Answer:
q=-5
Step-by-step explanation:
8q+6=4q-14
Remove q from one side
8q+6=4q-14
-4q -4q
4q+6=-14
Remove 6 from both sides
4q+6=-14
-6 -6
4q=-20
Divide 4 to isolate q
4q/4=-20/4
q=-5
Answer:
IJ = 34
Step-by-step explanation:
Since HK = JK, then IK is a perpendicular bisector and Δ is isosceles, then
IJ = HI , that is
2s = s + 17 ( subtract s from both sides )
s = 17
Then
IJ = 2s = 2 × 17 = 34
