Z is halfway between X and Y.

|XZ| = |ZY| and |XZ| + |ZY| = |XY|
That is, the length of XY is the same as the sum of the lengths of XZ and ZY, which are themselves the same as each other.
Zw < xyyw + wz = yzwy + wz = xz
The expression xy + z represents the sum of the product of x and y with the value of z. This is a simple algebraic expression where x and y are variables representing numbers, and z is a constant value. To find the result of xy + z, you would first multiply x and y, and then add the value of z to the product.
The only common factor to all terms is yz. → xy³z² + y²z + xyz = yz(xy²z + y + x)
xy + z = 9Subtract 'z' from each side:xy = 9 - zDivide each side by 'x':y = (9 - z) / x
If z is the midpoint of RT, it means that RZ is equal in length to ZT. Therefore, RZ = ZT. Additionally, the segment RT is twice the length of RZ (or ZT) since Z is the midpoint. Therefore, RT = 2 * RZ.
