Play machine can make 56 parts and 4 hours. it can also make 70 parts in 5 hours. write an expression that represents the number of parts of machine can make in the time in hours. predict how many parts of machine can make in 9 hours, 30 minutes.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
