What else can I help you with?
Evaluate 2xy when x equals 30 and y equals 2?
2xy=2*30*2=120
2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
Simplify 15xy-2xy-7x plus x equals?
15xy-2xy-7x+x=13xy-6x
Does 6xy-8xy equals -2x squared y squared?
No, it equals -2xy. lrn2math
What 2xy-3y plus 1 equals 0?
It's an hyperbola equation.
Why cant 2x plus y equals 2xy?
Because 2x+y is addition not multiplication
2cy plus 2xy equals 15 solve for y?
Y=15/(2c+2x)
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.
How do you evaluate 2xy times 9 if x equals 3 and y equals 2?
2xy*9 if x=3 and y = 2 2(3)(2)*9 12*9 108 You substitute x and y for their equivalent (3 and 2) then simply multiply 2*x*y, then multiply the answer of that by 9.
What is the greatest common factor of 2xy and 2x2y?
Since 2xy is a factor of 2x2y, it is automatically the GCF.
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
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
