The difference between 2x squared plus 4xy - 3 and x squared - 2xy - 4?
(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1
How do you factor 9-4x2 plus 4xy-y2?
(3 - y + 2x)(3 + y - 2x)
What is 2xy-2x-9x plus 3x?
[ 2xy - 8x ] is. Another way to write it is [ 2x(y - 4) ] .We can't tell what number it is unless we know the values of 'x' and 'y'.
2cy plus 2xy equals 15 solve for y?
Y=15/(2c+2x)
What is the perimeter of the rectangle in which A equals 2xymi?
The question doesn't nail it down; i.e., there can be several answers that satisfy the given information. Perimeter 'P' = 2 x (Length + Width) Area 'A' = (Length) x (Width) = 2 x y What is the Length, and what is the Width ? Here are five correct answers: ==> If the rectangle is (2) by (x y), A = 2xy, P = 4 + 2xy ==> If the rectangle is (2x) by (y), A = 2xy, P = 4x + 2y ==> If the rectangle is (x) by (2y), A = 2xy, P = 2x + 4y ==> If the rectangle is (1) by (2xy), A = 2xy, P = 2 + 4xy ==> If the rectangle is (0.1) by (20xy), A = 2xy, P = 0.2 + 40xy
