Answer:
zero because the discriminant is not a perfect square
Answer:
Therefore the dimensions of the garden is 16 feet by 13 feet.
Step-by-step explanation:
Let the length of the garden be x and the width of the garden be y.
Given that the area of the rectangular garden is 208 square feet.
Therefore,
xy =208

Again given that,
The garden is to be surrounded on three sides by a brick wall costing $ 8 per feet and the remaining sides by a fence costing $5 per feet.
The perimeter of the rectangle is = 2(length+ breadth)
= 2(x+y)
=2x+2y
The total cost of fence
![C= [ (2x\times 8)+(y\times 8)+(y\times 5)]](https://tex.z-dn.net/?f=C%3D%20%20%5B%20%282x%5Ctimes%208%29%2B%28y%5Ctimes%208%29%2B%28y%5Ctimes%205%29%5D)
= (16x+ 8y +5y)



To find the maximum or minimum point, we need to find out
and set
=0.

Then





Again 

Therefore at x= 13 , the cost is minimum.
Therefore x = 13 feet.
The other side of the garden is
feet = 16 feet.
Therefore the dimensions of the garden is 16 feet by 13 feet.
Answer:
when u distribute a number you are basically giving the number off and multiplying other factors by that number
Step-by-step explanation:
3(x+4) ( distribute the 3 ) so u would multiply the 3 by both factors ( the x and the 4) getting 3x+12
I'd do this in reverse order. Mult. each of the 3 terms inside parentheses by 4:
8k^2 - 28k + 12
Answer:
3.14*4^2*10≈502.65
Step-by-step explanation:
(The zero is in the tenths place and it doesn't round up)
The formula for the volume of a cylinder is V=pi*r^2*h
pi=3.14
r^2=Radius Squared
h=Height
I hope this helps!
