Answer:

Step-by-step explanation:

hello :

3x(x-y+z) + 2y (x+y-z)​ =  3x²-3xy+3xz +2yx+2y²-2yz

3x(x-y+z) + 2y (x+y-z)​ = 3x² -xy+3xz -2yz+2y²

Answer:

3x^2 + 3xz + 2y^2 - 2yz - xy

Step-by-step explanation:

(1) multiply it to get

3x^2 - 3xy + 3xz and 2yx + 2y^2 - 2yz

add similar variables (-3xy + 2yx)

( the order of the variables doesn't matter xy or yx is the same)

we get -xy

and then after that simplifying we get 3x^2 + 3xz + 2y^2 - 2yz - xy

Mike can stitch 7 shirts in 42 hours. he can stitch 1 shirt in how many hours, and in 1 hour he can stitch how much of a shirt.
podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = \frac{42}{7} = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = \frac{1}{6}  shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch \frac{1}{6} shirts.
