Answer is:9x^2-12y^2-11x in other words D
Explanation: find all the common variables and combine. In this case since your adding adding you would add 8x^1 and x^2 to get 9x^ then add -9y^2 and -3y^2 to get -12y^2. And so on to get the rest of the problem. One tip to help make this simpler is circle one type of variable like circling all the x^2, boxing all the y^2, and underlining all the x. Hope this helps

Answer:
D. $680
Step By Step Explanation:
100 pages are typed. Each page coast $5 to type.
100 x 5 = 500
40 pages are revised once. It costs $3 to revise a page once.
40 x 3 = 120
10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice
10 x 6 = 60
To find the total cost we add all the amounts together
500 + 120 + 60 = 680
The final answer is $680
