How many seconds in a day (working out please)

There are 86,400 :D

Step-by-step explanation:

Well, we all know there are 60 seconds in a minute. We also know there are 60 minutes to an hour. So, to find the answer of how many seconds there are in a hour then we times 60 by 60. So:

60 x 60 = 3600

Which, that means there are 3,600 seconds in just a hour. Then, we need to times by 24 because there are 24 hours in one day

So,

3,600 x 24 = 86,400

By the way, good luck on your test!

(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
