Question

I'll FAN & MEDAL!!!! Help pleaseeee
In the equation , the value of n is .

Answer 1

hold on

Answer 2

ok

Answer 3

try mathway

Answer 4

i got n=59

Answer 5

I got n=59 to.

Answer 6

Without mathway:
Square the left side getting:
n + 5 -2(n+5)^1/2(n-10)^1/2 + N - 10 square right side getting: 1
simplify left side, getting:
2n-5-2(n=5)^1/2 simplify further:
\[-2\sqrt{n ^{2}-5n-50}=-2n+6\]simplify further\[\sqrt{n ^{2}-5n-50}=n-3\]square both sides getting\[n ^{2}-5n-50=n ^{2}-6n +9\]Simplify: Getting: n=59

Answer 7

Mathway is easier, but you need to know how it was solved.
