Justin wants to use 376 ft of fencing to fence off the greatest possible rectangular area for a garden. what dimensions should h

Rina8888 [55]

Let the length be x and the width be y
the perimeter of the rectangle will be:
2x+2y=376
thus
y=188-x
thus the area will be:
A(x)=x(188-x)
A(x)=188x-x^2

For maximum Area A'(x)=0
from Area we shall have
A'(x)=188-2x=0
solving for x we get:
x=94
thus the width will be:
188-94=94
thus for maximum area the length=94 ft and width=94 ft
Area=94*94=8836 ft^2
thus the answer is:
<span>c. 94 x 94; 8836ft </span>

3x +x = 24

4x = 24

x = 24/4

x = 6

6 lions

6*3 = 18 monkeys

PLZZZZZZ HELPPPP MEEEE!!!!!!!!

To solve this we are going to graph each one of the system of equations. The points in which the graphs of the tow equations intercepts will be the real solutions of the system of equations.

System A. Since the graph of the equations intercepts two times, we can conclude that the system has 2 real solutions.

System B. Since the graph of the equation don't intercept, we can conclude that the system has 0 real solutions.

System C. Since the graph of the equations intercepts two times, we can conclude that the system has 2 real solutions.
