Answer:4) t+uv
Step-by-step explanation:
Well, if you're rounding to 1 significant figure, which you'll mostly be asked to do,
You look and see which number is the first one which isn't a zero. The most significant. In this example, the 8. You then need to look at the second number, it's a zero. It has no value and doesn't do anything to the 8. The number after that gets rounded down to a zero, it's too far away to effect the 8, and even if it could it's too low.
The answer is 8.

They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
<span>5x3 − 6x4
