Answer: 215.6 meters

Step-by-step explanation:

Formula of a polygon: A= 1/2ap

a = apothem

p = perimeter

Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9

A= 1/2 x 8 x 53.9

A = 215.6 meters

Can you help me please.

Answer:

option 2.

Step-by-step explanation:

You use the y-intercept form: y=mx+b

mx=slope, and b=y-intercept.

Looking at this graph, you can see that the slope is -2/3 (rise over run), and the line is negative, so the slope becomes negative.

So now, we can see the only option having the slop -2/3x is option 2.

I need help On these 8 questions that are blank
Ostrovityanka [42]

Answer:

X = 5

Step-by-step explanation:

3x + 12 + 9x = 72

okay hopefully i can explain so when your doing this combine like terms so

3x + 9x = 12x

12x + 12 = 72

then you would subtract both sides by 12

+12 = subtract x+12=2

- 12 = add x-12=2

there just flipped so in this case i would subtract 12

12x + ( 12-12) = ( 72-12 )

so 12-12 = 0 and 72-12 is equal to 60

12x = 60

the divide on both sides l but leave the x alone so its just 60 divided by 12 wich is 5

so X = 5

hope this helps with ur homework a little btw go back and redo ur other awnsers with this new concept hope it helps

Rose can run 4 miles in 56 minutes how many miles does Rosa run if she runs for 42 minutes
kogti [31]
\frac{56}{42} = \frac{4}{x}  then you figure out what you divide 56 by to get 4. which is 14. then you divide 42 by the same number 14.
