50 PTS JUST CHECK MY WORK 5x/2x-3 + -4x^2/3x+1
5x(3x+1)/2x-1(3x+1) + -4x^2(2x-3)/3x+1(2x-3)
foil each one
15x^2+5x-8x^3+12x^2/(2x-3)(3x+1)
simplify
-8x^3+27x^2+5x/(2x-3)(3x+10)
factor out an x
x(8x^2+3x+5)/(2x-3)(3x+10)
excluded values:
2x-3=0 3x+10=0
+3 +3 -10 -10
2x=3 3x=-10
/2 /2 /3 /3
x cannot=3/2 or -10/3

That's correct it actually helped me alot... Thanks

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
