Answer:
Step-by-step explanation:
Given,
Area of garden=456 square feet
Brick wall cost three sides 
per foot
fencing cost of one side
per foot
Let length and breadth of rectangular field is (l,b) feet
For minimizing the cost of material perimeter of garden should be minimum and area of garden is more.
Perimeter of garden
A=
A=
Differentiating the equation to find maximum area
To find 
again differentiating
The area is maximum when l=b
and perimeter is minimum
Cost material
Dimension of rectangular garden
for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More
<h3>For how many flyers is the cost at A-Plus Printers less than the cost at Print-and-More?</h3>
A-Plus Printers charges $26 plus $0.12 per flyer, so if you print x flyers, the total cost is:
f(x) = $26 + $0.12*x
For Print-and-More, they charge only $0.25 per flyer, so here the equation is:
g(x) = $0.25*x
Here we need to see for which value of x the costs are the same:
f(x) = g(x)
$26 + $0.12*x = $0.25*x
Now we can solve that linear equation for x:
$26 = $0.25*x - $0.12*x
$26 = $0.13*x
$26/$0.13 = 200
This means that for 200 flyers, the cost is the same in both places, then for 201 onwards we will see that the cost in A-Plus Printers less than the cost at Print-and-More.

Answer:
86
Step-by-step explanation:
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.
Answer:
2
Step-by-step explanation:
U have to use Pythagoras theorem to solve this.. (adjacent)^2+(opposite)^2=hypotenuse^2
looking at the question,
the hypotenuse =15ft
opposite =12ft
adjacent =???
adjacent^2+(12)^2=15^2
a^2+144=225
group like terms
a^2=225-144
a^2=81
introduce square root to both side
root a^2=root81
a=9ft
therefore, the answer is 9ft.
