Perfect Square Trinomials have first and last terms that are positive perfect squares. And the middle term is
twice the product of the square roots of the first and third terms.
First term:
n^2
Square root = n
Third term:
9
Square root = 3
9 * 1 = 9
9 * 2 = 18
18
-9
Therefore it is not a perfect square trinomial.

Hi there!
Say h = hours spent. We know Rachel finishes the job in 5 hours, thus, she finishes of the job in one hour. We also know Carl finishes the job in 8 hours, thus, he finishes
of the job in one hour. Working together, this would equal:
Now, this is the rate per hour. Thus, multiply this by h to get how much of the work is done in terms of hours spent, and set it to 1 to find how many hours it would take to finish 100% of the job.
Thus, it will take them approximately 3.0769 hours, or approximately 3 hours 4.614 minutes to finish the job together.
The equation to find volume is V=
r²h and you know all of your numbers other than h so you plug all that in. 30=3.14×1²×h → 30=3.14×1×h → 30=3.14×h → Divide both sides by 3.14 30÷3.14=3.14×h÷3.14 → 9.55cm=h
