The computer takes 12.19512.... nanoseconds to perform one calculation.
<em><u>Explanation</u></em>
The computer performs 8.2× 10⁷ calculations per second.
We know that, <u>1 second = 10⁹ nanoseconds</u>.
Suppose, the computer takes nanoseconds to perform one calculation.
So, the time taken to perform 8.2× 10⁷ calculations nanoseconds.
Thus the equation will be............
So, the computer takes 12.19512.... nanoseconds to perform one calculation.

Subtract the like terms:
6x^2 - 2x^2 = 4x^2
3x - -4x = 3x+4x = 7x
1 - 5 = -4
Now combine them to get the final answer:
4x^2 + 7x - 4
Triangle I think, I'm not too sure, but that is what I think
