6x plus 11 equals 92-3x?
6x+11=92-3x +3x +3x 9x+11=92 -11 -11 9x=81 divide by 9 x=9
How do you solve '3x plus 9 equals 81-5x'?
The problem '3x+9=81-5' can be solved as follows - 3x+9=81-5x Original Problem 3x=72-5x Subtract 9 from both sides of the equation 8x=72 Add '5x' to both sides of the equation x=9 Divide both sides by 8
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
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)
What is Plus 81 plus -6 plus -62 equals?
13
What is 9x squared minus 6xy plus y squared minus 81 factored as?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
3x2 plus 36x plus 81 What is the factor of the trinomial below?
(3X + 9) (X + 9)
Is 81 plus 0 equals 81 an expression?
no because it has an equal symbol in it
How do you factor 9x2-6xy plus y2-81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 (since the first three terms make a perfect square = (3x - y - 9)(3x - y + 9) since the expression now is a difference of two squares.
