igor_vitrenko [27]

Answer:

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

A=LW

where

L=(3x+1)\ ft

W=(3x-1)\ ft

A=35\ ft^2

substitute

35=(3x+1)(3x-1)

Apply difference of squares right side

35=9x^2-1

9x^2=36\\x^2=4\\x=\pm2

Remember that the length cannot be a negative number

so

x=2

<em>Find the length</em>

L=(3(2)+1)=7\ ft

<em>Find the width </em>

W=(3(2)-1)=5\ ft

Solve the exponential equation by the method of relating the​ bases, first rewriting the equation in the form
Nookie1986 [14]

Answer:

  x = 1/3

Step-by-step explanation:

Both bases can be written as powers of 6.

  36^x = (1/6)^(x-1) . . . . . . given

  (6^2)^x = (6^-1)^(x -1) . . . . . bases as powers of 6

  6^(2x) = 6^(-x+1) . . . . . . . . . simplify exponents

  2x = -x +1 . . . . . . . . . . . . . . . .equate exponents of the same base

  3x = 1 . . . . . . . add x

  x = 1/3 . . . . . divide by 3
