(f•g)(x) when f(x) =x^2+5x+4 and g(x)=1/(x+4)

x + 1

Step-by-step explanation:

f(x) × g(x)

= x² + 5x + 4 ×

=

factorise the numerator

x² + 5x + 4 = (x + 4)(x + 1) ← in factored form

=

cancel the factor (x + 4) on the numerator/denominator, leaving

(f · g)(x) = x + 1 ← in simplest form

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
