There are four terms in your algebraic expression.  Notice that the left two terms have the factors 2 and x in common, whereas the right two terms have the factors 3 and y in common:

2x(x-5y) + 3y(x-5y).  Can you now factor this further?  Note that the two terms here have a common factor, (x-5y).

Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
nydimaria [60]

Answer: For 10 sessions, the cost of the two plans the same.

Step-by-step explanation:

Let x= Number of sessions.

Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.

Total charge for x sessions = 50+30x

Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a  trainer.

Total charge for x sessions = 250+10x

When both plan charges the same, then

50+30x=250+10x\\\\\Rightarrow\ 30x-10x=250-50\\\\\Rightarrow\ 20x=200\\\\\Rightarrow\ x=10

i.e. For 10 sessions, the cost of the two plans the same.
