Answer:
(b) 2.71828 . . .
Step-by-step explanation:
If your calculator does not have an 'e' button, you can have it compute e^1 using the exponential function button.

e ≈ 2.718281828459045...
Like pi, 'e' is a transcendental number, a number that is not the root of any polynomial with integer coefficients.
7(4 + 5) = 63
28 + 35 fits the criteria for your question.
I think the answer is 33
