Written as a simplified polynomial in standard form, what is the result when (2x + 4)^2 is subtracted from 7x^2-10x-10?

The length of a rectangular board is 3 feet less than twice its width. a second rectangular board is such that each of its dimensions is the reciprocal of the corresponding dimensions of the first rectangular board. if the perimeter of the second board is one-fifth the perimeter of the first, what is the perimeter of the first rectangular board?

Find the inverse of each function for problems 1–6. state the domain and range of both the function and its inverse. restrict the domain of the function if needed. f(x) = –x2

Suppose "true-talent" average exit velocity (aev) on batted balls for all players is normally distributed with mean 86 mph and a standard deviation of 2 mph. for any sample of individual batted balls hit by one player, the standard deviation of exit velocity around a particular player's true-talent aev is 8 mph. at this point in the season, marco masher has a total of 10 batted balls with an average exit velocity of 94 mph. given only this information, the best estimate for his true talent exit velocity is closest to which whole number?
