## anonymous one year ago Is n = 7 a solution to this equation? 129 = 2n^2

1. UnkleRhaukus

The right hand side of the equation is $$2n^2$$. What does this become when $$n$$ is 7?

2. UnkleRhaukus

do you know what 7^2 is equal to ?

3. anonymous

12

4. UnkleRhaukus

$7^2 = 7\times 7 =?$

5. anonymous

Oh okay i got it thanks

6. UnkleRhaukus

so what does the right hand side of the equation become?

7. anonymous

98

8. UnkleRhaukus

so when n=7, the equation reduces to 129 = 98 (??!) Can n=7 possibly be a solution to the equation?

9. anonymous

No

10. anonymous

it said i got it right
