Answer:

so what you need to do here to check your work is to find 14 and 20 squared (which are 196 and 400) now your equation is 196 + 400 = c^2. now, you combine the like terms to make 596 = c^2. all you have to do now is find the square root of 596 (which is 24.4 when rounded to the nearest tenth). so yes, you are correct.

Answer:

  • $17,500 at 8%
  • $17,500 at 14%

Step-by-step explanation:

The fraction that needs to be invested at the higher rate is ...

  (11% - 8%)/(14% -8%) = 3%/6% = 1/2

Half the money should be invested at each of the rates:

  $17,500 for 8% return

  $17,500 for 14% return.

_____

If you let x represent the amount at the higher rate, then the total return is ...

  14%x + 8%(35000 -x) = 11%(35000)

  (14% -8%)x = (11% -8%)(35000) . . . . subtract 8%·35000

  x = (11% -8%)/(14% -8%)×35000 . . . . divide by the coefficient of x

Note that this formula is exactly the one we started with, above.

Write an expression in simplest form that represents the perimeter of the polygon ​
scoundrel [369]

Answer:

Perimeter = (11x + 12)

Step-by-step explanation:

Since, perimeter of a polygon is represented by the sum of measures of all sides,

Perimeter of the given polygon = 3x + (x + 10) + 5x + (2x + 2)

By adding like terms of the expression,

Perimeter of the polygon = (3x + x + 5x + 2x) + (10 + 2)

                                          = (11x + 12)

Therefore, expression for the perimeter is (11x + 12).
