Rob is making a square pen for his dog to play in. Each side of the pen is 30 feet long the formula for the area of a square is A = s2,where A stands for the area and s is the length of one side.
what is the area of the pen?
900 square feet
30 square feet
120 square feet
60 square feet
PLS HELP!

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

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

t hope this
