Plug the values into the second equation to see if they end up equaling 0.
-4: 2(-4)^2 - 6(-4) - 8 = 0
2(16) + 24 - 8 = 0
32 + 16 = 0
Not -4
-1: 2(-1)^2 - 6(-1) - 8 = 0
2 + 6 - 8 = 0
8 - 8 = 0
0 = 0
Yes -1
0: 2(0)^2 - 6(0) - 8 = 0
0 - 0 - 8 = 0
Not 0
1: 2(1)^2 - 6(1) - 8 = 0
2 - 6 - 8 = 0
-12 = 0
Not 1
4: 2(4)^2 - 6(4) - 8 = 0
2(16) - 24 - 8 = 0
32 - 32 = 0
0 = 0
Yes 4

Or use the quadratic equation ( - b +/- sqrt( b^2 - 4ac)) / 2a
————
a would be 2–
b would be -6–
& c is -8

Answer:
9.433981
Step-by-step explanation:
d=(−2−6)2+(−6−(−1))2−−−−−−−−−−−−−−−−−−−−−√
d=(−8)2+(−5)2−−−−−−−−−−−−√
d=64+25−−−−−−√
d=8–√9
d=9.433981
They give you the whole entire worth of the cage and it 30. so I believe it is s + 18.50= 30
Worked out
s + 18.50= 30
-18.50. 18.50
s = 11.50
