-- The smallest perimeter you can make with a certain area
is a circle.
-- The NEXT smallest perimeter with the same area is a square.
With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be
(13 bricks) x (3 bricks) .
= (13-ft) x (3-ft)
Perimeter = (2 x length) + (2 x width)
= (2 x 13-ft) + (2 x 3-ft)
= (26-ft) + (6-ft) = 32 feet <== shortest perimeter.
-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.
The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .
= (39-ft) x (1-ft) .
Perimeter = (2 x length) + (2 x width)
= (2 x 39-ft) + (2 x 1-ft)
= (78-ft) + (2-ft) = 80 feet .
What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.
The largest perimeter possible is 80ft.
What is the greatest perimeter that can be made?
The greatest perimeter is obtained when we put all the bricks on a single line. That is because in this case, we do not have internal bricks that do not apport to the perimeter.
In that case, we would get a rectangle that measures 39 ft by 1ft, then the perimeter is:
P = 2*(1ft + 39ft) = 80ft
The largest perimeter possible is 80ft.

it is not a function
for functions to work, there can only be one y value per x value aka if you see a set like this:
{(4,2), (6,5), (10,1), (3,6), (6,7)}
It is not a function because there are two y values (5 and 7) for one x value (6).

Answer: Method of finding the sum of 46 and 7 is mentioned in below explanation.
Step-by-step explanation:
According to the question, we have to find out 46+7
First, we need to add 6 and 7 by that we get the result 13.
Where, 3 will be the digit in once place of our answer.
And, we need to add 1 in 4, that is 5 by that we get the tenth place digit of our result. which is 5.
So, our complete answer is 53.

Answer: It has two pairs of parallel lines
Step-by-step explanation:
coordinates of E (-4,4) K (4,4) M(-6,-3) I( 2,-3)
The distance from E to K is 8 the same as the distance from M to I.
The distance from M to E is about 7.3 and the distance between K and I is the the same thing.
Answer:
Counting the unit on graph, we observes:
EK = MI = 8
EK // MI // x-axis
=> MEKI is parallelogram

The equation is P = 4S, with P being the perimeter, and S being a side.
Also, to get the length of a side from the perimeter, just divide the perimeter by 4.
