<u>Given</u>:
The given equation is 
We need to determine the exact solutions of the equation.
<u>Exact solution:</u>
The exact solution of the equation can be determined by solving the equation using quadratic formula,

From the equation the values are a = 1, b = -3 and c = -7
Thus, substituting these values in the equation, we get;



Thus, the exact solutions of the given equation is 
Hence, Option A is the correct answer.
Answer:
Step-by-step explanation:
5. is hypothenuse because it is across from the right angle
3. and 4. are legs
Multiply both 711.9 and 8.4 by 10 which will remove the decimal point.
and make the calculation much more easier
the required answer would be 84.75
