Answer:

  6 m, 6 m, 5 m

Step-by-step explanation:

If x is the common length then the perimeter is the sum of side lengths:

  x + x + (2x-7) = 17

  4x = 24 . . . . . . . . . add 7

  x = 6 . . . . . . . . . . divide by 4

  2x -7 = 12 -7 = 5 . . . find the length of the 3rd side

The side lengths are 6 m, 6 m, and 5 m.

The perimeter of a rectangle is 234 meters.
Licemer1 [7]

I am going to show you how easy this is. Once you understand, you will be able to do this forever.

:

Assuming the side of the rectangle are (L) length and (W) width, the perimeter:

2L + 2W = 234

:

"the rectangle is twice as long as it is wide,", the equation for this statement:

L = 2W

:

In the first equation, we can replace L with 2W, then we have

2(2W) + 2W = 234

4W + 2W = 234

6W = 234

Divide both sides by 6

W = 234%2F6

W = 39 meters is the width

:

Remember it said the length is twice the width, therefore:

L = 2(39)

L = 78 meters is the length

:

:

Check this by finding the perimeter with these values

2(78) + 2(39) =

156 + 78 = 234

Need help plz very much
andrew-mc [135]

Answer:

3

Step-by-step explanation:

Remember that when we are dividing two exponents with the same base (here, it's 13), we can subtract the values of the powers:

\frac{a^m}{a^n} =a^{m-n}

So, here, we have \frac{13^{10}}{13^7} , so we subtract 7 from 10:

\frac{13^{10}}{13^7}=13^{10-7}=13^3

Thus, 3 should go in the box.
