Answer:
The maximum area is
Step-by-step explanation:
Let
x----> the length of rectangle
y---> the width of rectangle
we know that
The perimeter of rectangle is equal to
we have
so
------> equation A
Remember that
The area of rectangle is equal to
-----> equation B
substitute equation A in equation B
This is a vertical parabola open downward
The vertex is a maximum
The y-coordinate of the vertex of the graph is the maximum area of the garden and the x-coordinate is the length for the maximum area
using a graphing tool
The vertex is the point
see the attached figure
Find the value of y
----->
The dimensions of the rectangular garden is by
For a maximum area the garden is a square
The maximum area is
The answer is A. So 25,700+3,000+700= 29,450. Then you subtract 29,450-6000= 23,450. So then A is your answer.
I hope this helps you. :)
Answer: 1 Ticket
Step-by-step explanation:
- You need to find the number from the percentage
I do this by moving the decimals 2 spaces back (Divide by 100)

20x0.05=1
Answer:
x = 2
Step-by-step explanation:
12x + 3x + 15 = 45
12x + 3x = 15x
15x + 15 = 45
45 - 15 = 30
15x = 30
30 / 15 = 2
x = 2
