Write the following conjugate binomial in standard form.
like this example.

(a) (x + 3) (x - 3)
= x( x - 3) + 3 (x - 3)
= x^2 - 3x + 3x -9
= x^ 2 -9

i have to answer b like this but i'm not sure if you have to repeat (x+5) twice or (x-5) considering the fact that it's written like this instead.

b) (x - 5 ) ( x + 5)

Which of the following describes how to translate the graph y = xi to obtain the graph of y = x - 11 - 12 1 unit left and 1 unit down 1 unit left and 1 unit up 1 unit right and 1 unit down 1 unit right and 1 unit up

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.)

Witch represents the inverse of the function f(x)=1/4x-12
