ruth is 6 years old
step-by-step explanation:
6 + 24 = 30, so 6/30 = .2
if you do 1/5 it also equals .2, so that is the answer.
(f - g)(x) = 5x^3 - 3
rearrange these functions vertically, with like terms in separate columns:
f(x) = 5x^3 - 2
g(x) = +1
now subtract, column by column:
570, the answer is 570, hope it
