Question

the square of x is = to 4 times the square of y. If x is 1 more than twice y , what is the value of x?

Answer 1

(2y + 1)^2 = 4y^2

Answer 2

2y + 1 = 4y^2

Answer 3

2y + 1 = 4y*

Answer 4

X=1/2

Answer 5

can i do that

Answer 6

report raver plz tired of trolls

Answer 7

what are you talking about

Answer 8

x = 4y^2
x = 2y +1

4y^2 = 2y +1

4y^2 - 2y -1 = 0

quadratic equation to solve for y

Answer 9

u cant help by giving out answers ,... kid just get out .. obv common sense . OBV TROLL OBV

Answer 10

whats wrong with my way?

Answer 11

you read the question wrong

it says that x = 2y +1

not x = (2y+1)^2

Answer 12

was plugign it in the original equation

Answer 13

x^2 = 4*y^2

Answer 14

then subsitutting x

Answer 15

with y

Answer 16

ohh is says the square of x at the beginning, okay i didn't see that

makes it much easier

Answer 17

2y +1 = 4y
1 = 2y

y = 1/2

plug that in for x = 2(1/2) +1

x = 2

Answer 18

yeah

Answer 19

the thing is thats not a answer

Answer 20

the answer is 1/2 but i still don't get how anyone can get that

Answer 21

sorry 1/4

Answer 22

@Preetha

Answer 23

x^2 = 4*y^2
x = 1 + 2y

Substitute the second equation in the first
(1+2y)^2 = 4y^2
1 + 4y + 4y^2 = 4y^2
4y = -1
y = -1/4

Substitute in y = -1/4 into the second equation:
x = 1 - 2/4
x = 1/2

Answer 24

can you tell me why my way is wrong plz
