Factor the four-term polynomial.
xz + x + yz + y

Nnnnneeedd 1.find the residual if you know the actual number is 5.2 and the predicted value is 4.8

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

What is the range for 31,39,29,34,37,24,36,33,34,28
