Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320
Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft
Answer:
I believe the answer is 1/2
Step-by-step explanation:
4*3=12+2=14,14/3
1*3=3+1=4
14/3+4/3=18/3 divided by 2=6/3 simplified to 1/2
I got the 6/3 by dividing 18 by 2 and 3 by 1
What do u need to do? add, subtract, multiply, or divide?
Answer: There are 5 red pencils, 16 blue pencils and 23 brown pencils.
Step-by-step explanation:
Since we have given that
Number of red pencils = 5
Number of blue pencils are 11 more than red pencils.
So, Number of blue pencils would be

Number of brown pencils are 7 more than blue pencils.
So, number of brown pencils would be

Hence, there are 5 red pencils, 16 blue pencils and 23 brown pencils.
