Answer:
x=8
Step-by-step explanation:
x + 1 = 9
Simplifying
x + 1 = 9
Reorder the terms:
1 + x = 9
Solving
1 + x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + x = 9 + -1
Combine like terms: 1 + -1 = 0
0 + x = 9 + -1
x = 9 + -1
Combine like terms: 9 + -1 = 8
x = 8
Simplifying
x = 8
Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so

- The length of the fencing is 80 meters, so

Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:

Then substitute for y in the first:

b) To maximize A, find the zero of the first derivative:

So y = (80-40)/2 = 20 meters.
