Question

Solve 3t(t+2)-3t^2 for t=19

I got 836.

Answer 1

so its

\[3 \times 19(19 + 2) - 3 \times 19^2 = 57 \times 21 - 3 \times 361\]

I think you need to check your answer

Answer 2

Yeah, I got a way smaller answer. Just work out the problem by swapping t with 19 and using PEMDAS.

Answer 3

I forgot about PEMDAS so I redid the problem and got 114.

Answer 4

Yes, that's the answer :)

Answer 5

thank you! :)

Answer 6

No problem.
