The perimeter is just the sum of all of the side lengths.
p=3x+4+x-10+5x-2
p=9x-8
Answer:
Step-by-step explanation:
The sum of the two costs is $52, so we can write ...
x + y = 52
The shoes cost $4 more than the jacket, so we can write ...
x - y = 4
These are your system of equations.
__
Subtract the second equation from the first:
(x +y) -(x -y) = (52) -(4)
2y = 48 . . . . . simplify
y = 24 . . . . . . .divide by 2
The cost of the jacket is $24.

is

![\frac{3}{4} * \frac{13}{8} = ?](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20%20%2A%20%20%5Cfrac%7B13%7D%7B8%7D%20%3D%20%3F)
, multiple by the reciprocal of the second fraction to get the answer.
There are two ways to do this. One is by adding up the squares, which takes a while. The other way is if you notice that the length along the bottom is the same as that long the top, and the same is true for the sides. While it does not appear this way at first, imagine that that was the floor plan of a house. If you looked at it from the side, you wouldn't see the dent in the corner, only one side. Since the length of the top is 13 units, from -7 to 6, and the side is also 13 units, from -6 to 7, the answer is
![13*2 + 13* 2 = 26 + 26 = 52](https://tex.z-dn.net/?f=13%2A2%20%2B%2013%2A%202%20%3D%2026%20%2B%2026%20%3D%2052)
52 units long.
