Sixty percent of the members of a study group are freshman, and 25 percent of those freshmen are Computer Science majors. If one member of the group is selected at random, what is the probability that the person selected is a Computer Science major

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
