Yes, xy is the same as yx, but should always be written as xy.
Area of a trapezoid = 0.5*(sum of parallel sides)*height
3x+5x
Improved Answer:If: x = -2 and y = -4Then: xy = 8Because: -2 times -4 = 8
It depends on where arc XY is: on a circles, a parabola or some other curve; and what else you know about the curve.
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
the sum of 3 times m and n
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
xy/-3
1/x+1/y y/xy+x/xy x+y/xy=12/24 12/24=1/2 1/2 is the answer.
(x+y+z)*3= Using the 'Order of Operation' rules, the addition within brackets is done first, then the sum is multiplied by 3 (thrice means three).
7+xy
1/x + 1/y y/xy + x/xy (y+x)/xy= 10/20 10/20=1/2 1/2 is the answer.
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
(a + b)/(xy)
Oh, dude, x times xy is just x squared y. It's like multiplying x by itself and then throwing in a y for good measure. So, if x was 2 and y was 3, you'd get 2 squared times 3, which is 4 times 3, which is 12. Math can be fun, right?
