How do you go back in Mordreds lair in poptropica?
just go to coordinates x=11 y=81
How do you factor 9x2-6xy y2-81?
(3x - y)(3x - y) - 81
How do you factor Y to the 8th power -81?
89
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
If the difference of the sum and difference of two numbers is 90 and if the sum of the sum and difference is 162 what are the numbers?
The answer is 45 and 81. To find it out you need to use double algebra. 1. (x+y)-(x-y)=90 x-x=0 y+y=2y/2= 1y=y 90/2= 45 y=45 2. (x+y)+(x-y)=162 y-y=0 x+x=2x 2x/2= 1x=x 162/2=81 3. check your work x+y-x-y=90 81+45-81-45=90- x+y+x-y+=162 81+45+81-45=162 81+45= 126 81-45=36 126+36=162 That is how you find the answer.
What is the square root of y to the second power over 81?
(y2/81)1/2 = y/9
What is y-56 equals 25?

What is the spanish word 81?
"Ochenta y uno" is the Spanish phrase for 81.
How would you factor 9x2 - 6xy plus y2 - 81?
9x^2-6xy+y^2 = (y-3x)^2 (y-3x)^2-81 -> ((y-3x)+9)((y-3x)-9)
How do you factor this Y3 plus 2y2 - 81y - 162?
y3 + 2y2 - 81y -162 = y2(y+2) - 81(y+2) =(y+2)(y2-81) = (y+2)(y-9)(y+9)
