Just confirming before answer, is this what the question lloks like 

Yolanda throws a sphere up in the air from the top of a building. After t² seconds, the height of the sphere above the ground is h² feet, where h=−16t²+30t+78. After how many seconds does the sphere hit the ground?

I had my doubts that it was related to physics but didn’t bother doing it

Physics or Maths

substituting 5 in the question doesn't give 2 times the dollars

I got the same answer on a rough page but looking at the answer I was like 'w*f is this'

I think if I answer any more math questions my mind will b**w up cuz its mixed with chemistry and maths and that a very bad mixture

25 is a messed up question but for 26 the answer is 5

by 'WTH' i thought u were trolling but there was actually a question, lemme have a look at it.

nevermind I got it.

$(t+1)(3t-3)=(3t-5)(t+2)$

Expanding gives

$3t^2-3t+3t-3= 3t^2+6t-5t-10$

Get the like terms together

$3t^2-3t^2 -3t+3t +5t - 6t=-10+3$

3t² cuts out and the remaining equals to -t but u are looking for a positive t so so multiply both sides by (-).

therefore this gives

$t=10-3$

$t=7$

So on Tuesday, u worked 8 hours and got 18$ and Andrew worked 16 hours and got 9 dollars. And also the question should be

'At the end of the day, I had earned two times more than he had. What is the value of t?'

WTH??
