Best Answer

If Y = y, then it is 9y4 or 9Y4. If Y is not the same as y, then you can't simplify it any.

x = 3y and x2 + y2 = 1600 9y2 + y2 = 1600 10y2 =1600 y2 =160 y = 12.65 in so x = 37.95 in, to the nearest hundredth of an inch

y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2

Yes, as x-y2=0

What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2

Yes, as x-y2=0

X2+y2=25 (x-8)2+y2 =41

To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
