The perimeter of the rectangle shown below is 24 feet. what's the length of side x? a. 3 feet b. 14 feet c. 6 feet d. 4 feet

4ft.

Step-by-step explanation:

Do the math ( 24ft.) If the top and bottom of the rectangle measure 8ft., and one side measure 4ft.; it’s a Guarantee that the other side measures 4ft as well... 8 + 8 + 4 + 4

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
