Answer:
3/4=3/4
Step-by-step explanation:
The perimeter is:
P = 2x + 2y = 80
The area is:
A = x * y
The area as a function of a variable is:
A (x) = x * (40-x)
Rewriting we have:
A (x) = 40x-x ^ 2
We derive the function:
A '(x) = 40-2x
We equal zero and clear x:
40-2x = 0
2x = 40
x = 40/2
x = 20 feet
The other dimension is:
y = 40 - x
y = 40 - 20
y = 20 feet
The area will be:
A = x * y
A = 20 * 20
A = 400 feet ^ 2
Answer:
The dimensions are:
x = 20 feet
y = 20 feet
The area is:
A = 400 feet ^ 2
Answer:
The correct line plot is choice C.
Step-by-step explanation:
If you look at the data values, you'll notice that there are three 
, and the only line plot that depicts this is choice C, so that is the correct answer.
To find the area of a square, do base times height.
If it is a square then all the sides are equal. Take 12 and divide it by 4 to find out that each side is 4 feet.
Base-4
Height-4
(4)(4)=16
Because it is normally set to only find real roots, not complex roots
if you are smart, you can use the factor function and use your head to find those roots
