Answer:

<u>Perimeter </u>

\bf \boxed{7+\sqrt{5}+\sqrt{8}+\sqrt{10}}

Step-by-step explanation:

Draw the polygon to have an idea of what you are being asked.

<h3>See picture attached </h3>

Now find the length of each side and add them up, that is the perimeter.

To find the length of a side use the formula of the distance between to points (a,b) and (c,d)

\bf \sqrt{(a-c)^2+(b-d)^2}

<u>Distance between (-2,1) and (-3,3) </u>

\bf \sqrt{(-2-(-3))^2+(1-3)^2}=\sqrt{5}

<u>Distance between  (-3,3) and (-1,5) </u>

\bf \sqrt{(-3-(-1))^2+(3-5)^2}=\sqrt{8}

<u>Distance between  (-1,5) and (2,4) </u>

\bf \sqrt{(-1-2)^2+(5-4)^2}=\sqrt{10}

<u>Distance between (2,4) and (2,1) (obviously 3) </u>

\bf \sqrt{(2-2)^2+(4-1)^2}=3

<u>Distance between (2,1) and (-2,1) (obviously 4) </u>

\bf \sqrt{(-2-2)^2+(1-1)^2}=4

Add up all the lengths

\bf \sqrt{5}+\sqrt{8}+\sqrt{10}+3+4

<u>Perimeter </u>

\bf \boxed{7+\sqrt{5}+\sqrt{8}+\sqrt{10}}

PLS HELP ME THIS IS HARD
SOVA2 [1]

Answer:

1 dollar is equal to 0.75 E

Step-by-step explanation:

120$ = 90 e -----> 4$ = 3E

250$ = 187.50 e -----> 4$ = 3E

400$ = 300 e -----> 4$ = 3E

----------------------------------

from this we know 4$ = 3E

1 E = 4$/3

1 E = 1.33...$

---------------------

1 $ = 3/4 E

1 $ = 0.75 E

---------------------

1.33...$ dollars is equal to 1 E and

1 $ is equal to 0.75 E

-----------------------------------

90 x 1.33... =120

187.50x1.33...= 250

300 x 1.33... = 400

--------------------------
