Answer 7

What do you think?

Answer 8

A and F

Answer 9

A AND F

Answer 10

yo still there ilfy214

Answer 11

I honestly don't know... I'm trying to work it out

Answer 12

ok

Answer 13

how did you get A and F?

Answer 14

so not F, right?

Answer 15

√(2x + 3)² = ±√10
2x + 3 = ±√10

Finally...

x = (-3 ± √10)/2 [A and F]

Answer 16

so what do you think

Answer 17

yes...

Answer 18

ok cool

Answer 19

im guessing.. you know. lol

Answer 20

Because I got \[x = -3/2 \pm \sqrt(5/2)\]
