B.
Because when doing the math, letter B fits the criteria of a quadratic equation. Which is ax^2 + bx + c = 0.
A is wrong because if we were to do the math, there would be no ax^2. The most important thing in a quadratic equation is the term ax^2, bx and c do not matter as much.
C is wrong because there cannot be a greater exponent than ^2.
D is wrong because of the same reason as letter a.
Its already in simplest form but you can convert it to a mixed fraction and get:
1 5/8
Answer:11 and 27
Step-by-step explanation:
11+16=27 and they are 16 years apart and because it says 5 years 27+5=32 and if you add 5 to 11 you get 16 and 16+16=32
