How does using scientific notation help when computing with very small or very large numbers ​

It abbreviates or shortens the numbers that you are working with making them easier to do calculations with.

Step-by-step explanation:

Example : 10,000 in scientific notation = 1.0x10^4

1,000,000 = 1.0x10^6

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
