Be sure to answer all 5 parts of the constructed response. (1 point for each part) The area of a large state park that is in the shape of a square has an area of 196 square miles. The park service wants to construct a road that travels the perimeter of the park.

If x is one side of the park, what equation can you set up to find the length of a side?
How many solutions does the equation have that you wrote?
Will all of the solutions make sense in the context of the problem? Explain your answer.
Solve the equation for x.
Determine the perimeter of the park.

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
