Answer:
second answer - think im right
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
6x+9=3x+12
6x-3x=12-9
3x=3
x=1
The perimeter for this case is given by:

Substituting values we have:

The area is given by:

Writing the area based on a variable we have:

We derive the area to obtain the maximum of the function:

We equal zero and clear x:

Then, the other dimension is given by:

Finally the maximum area is:

Answer:
The length and width of the plot that will maximize the area are:

The largest area that can be enclosed is:

Answer:
1. 100
2. 10
Step-by-step explanation:
There are 100 different outcomes because each number can pair with another number 10 times or an easy way to do it is just to do 10x10 which is 100.
For number 2 the answer is 10 because each x and y have one number that is the same for example x and y both have 1,2,3,4,5... and so on. So therefore each number can pair to itself once and the numbers are 1-10.
