Let say the length of the rectangle is x. The material that can be used would determine the perimeter of the rectangle. Using the perimeter formula you can find the rectangle width
perimeter= 2(width+length)
400= 2(width + x)
200= width+x
width= 200-x
The function to determine the area would be:
area= length * width
area= x* (200-x)
area= 200x- x^2
To find the highest area you need to find out the vertex by finding the value of x when the differentiate of the function equal to zero.
dx/dy= 200- 2x = 0
2x= 200
x=100
If you put x=100 into the area function you will find
area= 200x- x^2
area= 200(100)- (100)^2
area= 20,000 - 10,000= 10000 feet^2
The upper number is NUMERATOR and below one is DENOMINATOR
Answer:
f(x) = 2x + 10
Step-by-step explanation:
Or <em>y = 2x + 10</em> considering the question requests it...
2x = $2 per each ride

Answer:
Step-by-step explanation:
Answer:
"x+1, x + 3"
Step-by-step explanation:
Consecutive even numbers' example would be:
2, 4, ...
16, 18....
212, 214...
What do they have in common?
They are spaced "2" units apart.
4 - 2 = 2
18 - 16 = 2
214 - 212 = 2
Now, let's check for the answer choices, whichever is "2" units apart, that is the one.
x + 2 -(x + 1) = x + 2 - x - 1 = 1 units
x+3 - (x+1) = x + 3 - x -1 = 2 units [this is the one]
2x + 1 - (2x) = 2x + 1 - 2x = 1 units
Hence, 2nd answer choice is representing consecutive even integers.
