1. a+b/2 = a+4/a - solve each equation

2.4/3n + 2/n+1 + 2/ n squared + n . reduce to lowest terms

3.use product and quotient rule to simplify --square root of 27/16

ok i cant seem to set this problem up correctly...
A fence 8ft tall runs parallel to a tall building at a distance 4 ft from the building. What is the length of the shortest ladder that will reach from the ground over the fenceto the wall of the building?

so what i am trying to do is get the minimum value of the equation i am trying to set up...

Do the equations y = -4x and y = 4x have graphs that are perpendicular lines ? I say no, because in order for two equations to have graphs that are perpendicular lines, their slope must be the negative reciprocal of eachother. That is not the case with these two equations. Am i right ?

this was my question:

directions: solve the following inequality algebraically.
absolute value 2x-1>3.6
so 2x-1 is an absolute value
3.6 is not an absolute value

i recieved several answers but they all kinda make sense to me....
they were
x= 2.3 and -1.3

x>2.3

x<1.3

x is either greater than 2.3 or less than -2.3

x>2.3, x<-1.3

x > 4.6/2 or |2.3|

which one is right?
answer only if u are sure

Suppose this game can continue indefinetely. One of the players has the rationals, the other the irrationals. The one with the rationals chooses a subinterval I1 = [a1 , b1] of [0, 1] (a1 e b1 may be rational or irrational) with length b1 - a1 <= 1 = 1/1. On the next move, his opponent chooses a subinterval I2 = [a2, b2] of I1 with length less or equal to 1/2. On the n-th move, it's chosen a subinterval I_n = [a_n, b_n] of I_(n-1) with length b_n - a_n <= 1/n. So, 2 sequences a_n e b_n are constructed in [0,1], such that a_n < b_n for every n and lim (a_n - b_n) = 0 Since the reals are a complete set, a_n and b_n converge to a same x in [0,1] (ie, x is the only element common to all of the I_n's). If x is rational, the player with the rationals wins, and vice-versa. Show that there exists an strategy that, if followed by the player that has the irrationals, assures his victory no matter the moves of his opponent are.

However the algebra is messing me up.

This is the problem:
The the derivative of
((x+1)(x+2))/((x-1)(x-2))

Thus I use the quotient rule:
Which is

((2x+3)(x^2 -3x - 2) - (2x -3)(x^2 +3x +2)) / (x^2 - 3x - 2)

As I expand the top and do the math I end up with :

-6x^2 - 8x, However it's suppose to be -6x^2 + 12...

Where did I go wrong?

Answer in back of the book:

(-6x^2 + 12) / (x^2 - 3x - 2)

It is a perfect circle. The center is labeled as point (5,0)
And if you drew this out then from the center you would draw a diagnol line to a place in the top right part of the circle. (on the Line)

How are you supposed to find the area in terms of Pi???????
