The following steps are used to rewrite the polynomial expression (x+2y)(x-5y) step 1: x(x-5y)+2y(x-5y). step 2: x^2-5xy+2yx-10y^2. step 3: x^2-5xy+2xy-10y^2. step 4: x^2-3xy-10y^2 identify the property used in each of these steps.

What is the solution of the systems of equations? y=2/3x+3 x=-2

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

In a small section of a stadium there are 40 spectators watching a game between the cook islands and fiji. they all support at least one of the two teams. 25 spectators support the cook islands and 16 of these support both teams. how many support only fiji?
