First Number: x
Second Number:  2x + 5 (Five more than twice the other)

Mathematical Sentence/Equation:

(x) + (2x+5) = 36

3x + 5 = 36

3x = 36 - 5

3x = 31

x = 31/3   or   10  \frac{1}{3}

ANSWER:

A)  NO.  This is not a quadratic equation, because the leading term, 3x, is raised only to one or has the power/exponent of 1, that is, it is a first degree polynomial.  Quadratic is a second-degree polynomial.

B)  Mathematical Sentence:
     (x) + (2x + 5) = 36
     
     Simplified:
     3x + 5 = 36
     3x = 31

thank you for the correction MomGie
You're welcome. The other user (Arahdhj) may have confused the operation to be used. He has answered correctly 75% of Math problems here, as of this writing :-)
