The answer would be 3.4
Hope that helped : )
To find the length of a side of a square fins the square root of the area.
Area = 200 cm^2
Side = √200
Side = 10√2 (Exact length)
or 14.142 cm's ( round the decimal answer as needed.)
The name of the answer I put down is 15
<u>Given:</u>
The given function is 
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by

Reflecting the function over the x - axis, we get;

Multiplying -1 to both sides of the equation, we have;

This can be written as

Hence, the reflection of the function over the x - axis is 
Thus, Option A is the correct answer.
1342:215 is the ratio take the first number you get and put it over the 215. Ratios are often expressed as fractions, so 1342/215 would be correct as well.
