Is 2xy the same as 2x2y?
yes * * * * * No, it isn't. 2xy = 2 times x times y. Depending on which you mean: 2x2y = 2 times x times 2 times y = 4xy; OR 2x2y = 2 times x times x times y.
Simplify 8 -x 2y you 2y - x?
8-x2y 8-2xy 2xy-8
2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
What does 2xy mean does it mean 2x x2xy or 2x 2x4x 2y 2y4y then multiply or add?
it means two times x times y.
The sum of x and y squared?
You can expand (x + y)2 into x2 + 2xy + y2
How do you write four times the product of x and y decreased by 2xy?
4xy - 2xy
What is 2 times the sum of x and y?
2xy
2xy + 2xy squared?
(x + 4y)(x - 6y)
Is 2xy the same as 2x2y?
yes * * * * * No, it isn't. 2xy = 2 times x times y. Depending on which you mean: 2x2y = 2 times x times 2 times y = 4xy; OR 2x2y = 2 times x times x times y.
Simplify 8 -x 2y you 2y - x?
8-x2y 8-2xy 2xy-8
2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
Would five times x times two times y divided by five cancel the fives?
it would equal 2xy
What is x times 2y?
'x' times '2y' is written as '2xy'. In Algebra. Addition is shown as 'a + b' '. Subtraction is shown as 'a - b' Multiplication is shoewn as 'ab' (NB no multiplication sign 'x', as it might be confused with the unknown 'x'. Division is showen as a/b ( like a fraction). NB '2y' means '2' Times 'y' So overall 2 X y X x = 2xy . Notice ; for clarity ,I have put in 'capital ' 'x' for multiplication. However, hopefully you can see that it may become unclear which is the unknown 'x'.
Simplify 15xy-2xy-7x plus x equals?
15xy-2xy-7x+x=13xy-6x
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.
Prove '2xy is less than equal to x square plus y square'?
(x-y)2 is a square so (x-y)2 >= 0 expanding, x2 - 2xy + y2 >= 0 so x2 + y2 >= 2xy or 2xy <= x2 + y2
what is the answer for (x+y)(x+y)=?
X²+2xy+y²
