No prob

2. anonymous

cool! so you can help?

2 sqrt(5x-4)-3=11

4. anonymous

Is there a question?

5. anonymous

i need to solve that

6. anonymous

2 (5x-4)^(1/2) = 14 (5x-4)^(1/2) = 28 5x-4 = 784 5x = 789 x= 789/5

7. anonymous

Lol nvm. that's wrong it should be divide by 2

8. anonymous

oh so 789/2?

9. anonymous

2 (5x-4)^(1/2) = 14 (5x-4)^(1/2) = 7 5x-4 = 49 5x = 53 x= 53/5

10. anonymous

ohh ok

11. anonymous

I accidently multiplied both sides by two before... this is the right answer

12. anonymous

$\int\limits_{\sqrt{(\cos^{-1} & ? \ ? & ?)}}^{?}$

13. anonymous

is there like a special calculator you use or are you just that good?

14. anonymous

Just follow the orders of operations and solve... I guess you could use a graphing calculator to solve this, but this problem doesn't require one (and I didn't use one for this problem either)

oh ok. i just lack math abilities! lol
