Show that (X+1)(x+3)(x+5) can be written in the form ax^3+bx^2+cx+d

(x+1)(x+3)(x+5) = x^3 + 9 x^2 + 23 x + 15

Step-by-step explanation:

If you apply the distributive property, you can expand the expression to x^3 + 9 x^2 + 23 x + 15, from that you can see that:

a = 1

b = 9

c = 23

d = 15

And with these values, ax^3+bx^2+cx+d completely equals the given expression.

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.
