7. Find the least number which when divided by 33, 44 and 55 leaves remainders 31, 42
and 53, respectively.

whats the

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
