Plzz help!!!!!!!<br>I 'll give brain liest​
Basile [38]

Answer:

Step-by-step explanation:

1. 3x2 + 5x - 4 + 6x2 - x + 7

= combining like terms

= 9x2 + 4x + 3

2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y

= 5y2 - 10y + 1

3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2

= - x2y - 5xy2

4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2

= 2x2 - 8xy + 6y2

Hey there! Hello!

For this problem, you first need to figure out how many questions Nicholas got right, got wrong, and didn't answer. Then, you need to compare these to how many points he gets for each one. To do the first thing I mentioned, you need to add together how many problems your question accounts for, then subtract these from 100 and assume that these are questions he got wrong. 

86+6=92
100-92=8

So, he has a total of 86 problems correct (times 1 will be 86 points added to his total score), 6 problems unanswered (times 0 will be 0 points that won't affect his score), and 8 problems incorrect (times –1/4, or –0.25, will be 2 points taken away from his total score). 

Then, plug them into an equation. Since the unanswered questions don't count for anything, they can be omitted.

86+(-2)=84

Your final answer will be C. 

Hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
