2 because 8-6 is 2 and a Richet Scale I dont Know
Make sure to multiply everything together, then check it with a calculater.
Hope this works:)
If you would like to simplify the difference <span>(–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x), you can do this using the following steps:
</span> <span>(–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x) = -7x - 5x^4 + 5 + 7x^4 + 5 + 9x = 2x^4 + 2x + 10
The correct result would be </span><span>d. 2x^4 + 2x + 10.</span>
