What is the answer to this math question 3xy-xy-2y plus 5y?
That equals 2xy + 3y which factors to y(2x + 3)
The area of a rectangle is given by A equals 6x2y plus 4y2x and the width of the rectangle is w equals 2xy What is the length L of the rectangle if L equals A w?
L = 3x + 2y
2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
What is xy plus xy?
xy + xy = 2xy
3x squared plus 6xy plus 3y squared?
3x2+6xy+3y2= 3(x2+2xy+y2)= 3(x+y)2
2cy plus 2xy equals 15 solve for y?
Y=15/(2c+2x)
Simplify 15xy-2xy-7x plus x equals?
15xy-2xy-7x+x=13xy-6x
How do you solve 8 plus x2y?
i don't get that if it is 2xy +8 or 8 + 2xy then you can't solve or simplify it any further if it were 8 x 2y then you time the 8 by the 2 to get 16y
When x-y equals 7 and xy equals 8 find the value of x square plus y square?
x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65 You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.
What 2xy-3y plus 1 equals 0?
It's an hyperbola equation.
How do you solve 2xy plus 6 equals 4xyz for y?
2xy + 6 = 4xyz Divide through by 2: xy + 3 = 2xyz 3 = 2xyz - xy = y*(2xz - x) Therefore, y = 3/(2xz - x) provided that 2xz - x is not zero.
Why cant 2x plus y equals 2xy?
Because 2x+y is addition not multiplication
How do you solve 4x-y2 and 3x y5?
4x-y2=2xy 2x ? y5 if its plus its 7 xy
What is 2xy plus 6xy?
2xy + 6xy = 8xy
Whats the factor from of 2xy-4x plus 8y-16?
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
Evaluate 2xy when x equals 30 and y equals 2?
2xy=2*30*2=120
Solve for y if the equation is -2x - 2y equals -12?
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
