Thank you Margie. I got 1 wrong but you helped me thanks
To the person who said to study. Your probably a stupid teacher that does indoor recess in elementary. We try out best and fail to do good from our teachers teaching and this helps and check our answers. Please re consider saying that

FORMAT WRONG ABOVE.... Correct one is.. Find dy/dt when y = 2x^2 + 2x + 4 and dx/dt = 14 when x = 7.
c)3! x 6! The three must remain together but can be in any permutation with the rest. It would be 5! ways if the three books had to be in a certain position.
I think its $990 after Cellularphoniqua takes 10%
Anyone please?
I figured it out. 40 acres = 1320' x 1320'; P=2L + 2W; P=2(1320)+ 2(1320); P=5,280', which is a mile. Run the wire 3x, and it equals 3 miles.
I figured it out. 120-100=20, which is the net difference. Divide net difference by the new cost of 120, which equals 16.67 less.
I can't calculate the correct answer.
Thank you for the response. That was the answer that I initially calculated using percentage change; however, the answer is that it was lowered by 16 2/3%. The explanation is that it now takes $6 to buy what used to cost $5. Each dollar is worth 1/6 less.
