Answer:

width=7 cm

Step-by-step explanation:

perimeter=2(lengths+width)

        56   =2(21+x)

         56  =42+2x

   56-42  =2x

        2x    = 14

            x   =7    

therefore the width=7 cm

Answer:

45/126 or 5/14

Step-by-step explanation:

a / b = 5/8

b / c = 9/14

a = 5

b = 8

b = 9

8 * 9 = 72

b = 72

If b was = 8 and now = 72, multiply a by 9.

b = 45

If b was 9 and now is 72, multiply c by 9.

c = 14 * 9 = 140 - 14 = 126


b / c = 45/126 or 5/14

You are welcome!

Let f(x)=8/(1+3e)^(-0.7x)
Troyanec [42]
For x = -3, <span>(-0.7x) equals (-0.7[-3]), or 2.1.
 
                                8                   8                       8
Then f(-3) =  ------------------- = ---------------- = ------------ = 0.31 (approx)
