Multiply 18hours by 60 seconds, the answer is 2880 seconds.
-18(1) = -18,right?
4(3) = 12, right?
-18 - 12 = -30
From the looks of it, we had to "Subtract" the outcome of each problem that we went over
You're correct: -30 (option A.) would be your answer
What is it that you are looking for ?
x or y ?
A^2+b^2=c^2
160^2+160^2 = 51,200
Square root of that is <span>226.27416998</span>
