29-30. Mr. Santos plans to construct a circular dinner table with a square centerpiece in the center. The radius of thetable should be the same measure as the side of the square centerpiece. Write an expression for the remaining area ofthe table not covered by the centerpiece in terms of the side of the square. Write your answer in factored form. (3pts)

you can't solve x because it is 2 linear equation and you only have one equation

the answer is b.

step-by-step explanation:

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
