What is -10t3 plus 3t plus 50 equals?

Answer 1

Whenever you have a variable (in this case, t), and you don't know the value of it, your answer will have the variable in it.

So, if I had -10t's, and 3t's, that leaves me with -7t's.

So, the answer would be -7t+50 (you can't reduce it any further than that, because you don't know what t is)

So, if you have two variables, such as 3a + 2a, the answer would be 5a.

If it was 3a + 2a +50, it would just be 5a + 50, because you don't know what "a", is, therefore you can't multiply it.

I hope that made sense.
