Answer:
Distributive property
Step-by-step explanation:
60
30+30=60
{y≥3x−2
{x+2y≤4
First, multiply the first equation by 3 to get:
Then, add the two equations together to get
We can follow that x=2. Plugging in x=2, we get that y=-4.
Therefore, the solution of (2,-4)
The area should be "210 cm to the second power"
