SHE BLOCKED ME AFTER 8 MEDALS

Answer 11

why?

Answer 12

IDK

Answer 13

The question begs if you're looking for \[4y^2 +8 = 264\] or your original equation.

Answer 14

did she give you the wrong answers?

Answer 15

@cvliboi
Subtract 8 from both sides.

Answer 16

1 WRONG IN CRODENT GEMORTY

Answer 17

oh sorry yea that's the equation @_Squish

Answer 18

o.o

Answer 19

Here are the steps you'll like to solve in order to get your equation, as probably mentioned by previous users (I'm a very lazy person therefore I don't check all the comments above)
1. You'll want to remove 8 from both the left and right side of the equation.

2. After that, division of 256 / 4 will get you a step closer.

3. Find the square root of 64 to finalize your answer of 8. Turns out Yajna was right.

Answer 20

@cvliboi to demonstrate exponents use "^"
Such as 4y^2

Answer 21

I thought it would do it by itself @Afrodiddle

Answer 22

i know @_Squish

Answer 23

nope :P

Answer 24

Sorry @yajna
Btw... why did you block that one person? o.o

Answer 25

\[y^{2}=256/4\]\[y ^{2}=64\]\[y =\pm 8\]

Answer 26

Verify that both plus and minus 8 satisfies the equation.

Answer 27

4y^2 + 8 =264
4 y^2 =264-8
4 y^2 =256
y^2 =256/4
y*y=64
y*y=8*8
y=8
or
y*y=-8*-8
y=-8
ans 8 or -8
