Answer:
390=W 195=L Area=76050
Step-by-step explanation:
You have two lengths and one width for your perimeter
P= 2L + W
you are given your perimiter 780
780= 2L + W
To solve for your maximum Width
780-2L=w
Area is L * W
A= (780-2L)*L
A= 780L - 2L^2
the derivitive of the Area
A' = 780-4L =0
add 4L to both sides
780=4L
divide by 4 on both sides
195=L
Bring back 780-2L=W and plug in what you now know is L
780-2(195)=W
780-390=W
390=W
X/4+3.5>5
x/4+3.5-3.5>5-3.5
x/4>1.5
x/4(4)>1.5(4)
x>6
You have to add these together to find the total number of quarts she made. 8+5+5= 18 quarts of soup. if everyone gets one cup, then 18 people is able to get soup. the answer is 18 guests
