Answer 1

Answer:

first we have to bring (4x + 1) (x + 4) back to ax^2 + bx + c form

(4x + 1) (x + 4)

= 4x(x + 4) + 1(x + 4)

= 4x^2 + 16x + 1x + 4

= 4x^2 + 17x + 4

as we can see  4x^2 + 17x + 4 is in ax^2 + bx + c form

so we can also see that a = 4, b = 17, c = 4

so a + b + c = 4 + 17 + 4 = 25

so the answer is d) 25
