S i'll give 20 points Show all work to factor x4 − 5x2 + 4 completely.

please EXPLAIN how to do it, don't just give me the answer and leave it at that.

Add 1/7 + -1/7 your answer should be reduced to its smallest form and should not be an improper fraction

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
