answer is 11/3.
HOPE THIS HELPS
mark me brainleist pls
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
2x2 is 6
4x6 is 24
6 divided by 24 is 0.25
Answer:
the first should be a valid generalization should be sample 3, the least likely I think is the one you chose, and then I'm pretty sure you got the next, and the one after that right
