Let s represent the length of one side of this rectangle, and w represent the width of the rectangle (length of one end). Then 2s + 2w = 12 units, and the area is a = s*w. Using the previous equation we can eliminate either s or w. Since we want s, eliminate w: 2w = 12 - 2s, or w = 6 - s.
Then the area of the rect. is a = s(6 - s) = 6s - s^2.
You have not shared the actual area of the rect., but have represented it by "a."
Suppose that the area is given and is 90. Then 90 square units = 6s - s^2, so that -s^2 + 6s - 90 = 0. Using the Pyth. Thm., we find s as follows:
-6 plus or minus sqrt( 6^2 - 4(-1)(-90)
s = ---------------------------------------------------
2(-1)
Unfortunately, s would come out as a pair of complex numbers, which is not possible in a situation where you're calculating lengths.
Please recheck this problem. Was the aera of the rectangle, a, given?
The solution to this problem is (-2,0). Your welcome, and yes im positive this is the correct answer.
Answer:
400
Step-by-step explanation:
6x + 800 = 3200
6x = 3200 - 800
6x = 2400
= 2400 / 6
x = 400
Hope this answer helps you :)
Have a great day

Answer:
3 cups
Step-by-step explanation:
2/12 = 1/6
1/6 * 3 = 3/18
3 out of 18 cups, so 3 cups.
A value that "lies outside" (is much smaller or larger than)
