If th equestion meant: (x+y+z)^2
The expansion is:
(x+y+z)^2= x^2+2xy+y^2+2yz+z^2+2zx

If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
X plus y plus z is a trinomial or not?
Yes.
What is the ordered triple of x plus y plus z equals 12 and y equals 1 and x-y-z equals 0?
x + y + z = 12 y = 1 x - y - z = 0 Substitute y = 1 in the other two equations: x + 1 + z = 12 so that x + z = 11 and x - 1 - z = 0 so that x - z = 1 Add these two equations: 2x + 0z = 12 which implies that x = 6 and then x + z = 11 gives z = 5 So the solution is (x, y, z) = (6, 1, 5)
What is x plus y to the second power plus z to the second power?
(x+y)^2+z^2=x^2+y^2+z^2+2xy or ((x+y)^2+z)^2= (x^2+y^2+2xy+z)^2= x^4+y^4+z^2+6x^2y^2+4x^3y+2x^2z^2+4xy^3+4xyz^2+2z^2y^2
Z2 equals x2 plus y2?
What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?

What is xy cubed z squared plus y squared z plus xyz completely factorised?
The only common factor to all terms is yz. → xy³z² + y²z + xyz = yz(xy²z + y + x)
How do you find the side to a right triangle if only one leg and the hypotenuse is given?
re x and y and hypotenuse z then x squared + y squared = z squared If you know x and z, then y sqrd = z sqrd-x sqrd and thus y = square root of (z sqrd -x sqrd)
What is the property x plus y plus z equals x plus z plus y?
x + y + z = x + z + y is the commutative property of addition.
Are the answers to area of triangle squared?
It is 1/4*base2*(vertical height)2 in units of length to the fourth power. If the lengths of the sides are X, Y and Z, then the area squared is (X + Y + Z)*(- X + Y + Z)*(X - Y + Z)*(X + Y - Z)/16
What is answers z plus y plus x?
That depends on the values of 'z', 'y', and 'x'.
What was the formula for Pythagoras famous theorem?
x squared + y squared = z squared.
How do you factorise brac x-y brac squared - z sqaured brac. stands for bracket?
(x - y)2 - z2 is a difference of two squares (DOTS), those of (x-y) and z. So the factorisation is [(x - y) + z]*[(x - y) - z] = (x - y + z)*(x - y - z)
How do you simplify open parenthesis x squared y close parenthesis times open parenthesis y z close parenthesis times open parenthesis x y z close parenthesis?
x cubed y cubed z squared
True or false x plus 2y plus 3z is equivalent to z plus y plus z plus x plus y plus z?
True
What is 4x cubed y cubed z divided by x negative squared y negative 1 z sqaured?
4x cubed y cubed z divided by x negative squared y negative 1 z sqaured = 4
If x plus y plus z equal 84 and x plus z equals 72 and x plus y equals 52 solve what is x what is y what is z?
y=84-72=12 z=84-52=32 x=84-12-32=40
