Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15
Since the distance from the two known coordinates are known, you can find the slope of the line (for lack of a better word) to work backwards. there is a +5 unit gap between -21 and -16, so the next number would be -26. So, without havint to do any more work, the answer is B.
Hi There!
Ok, so student council needs 500 dollars from flower sale, and they already have 415, To find how much they need you have to subtract 500-415, your final answer should be 85, so the student council needs $85 dollars more to reach their goal.
Hope This Helps :)
