Answer:
Step-by-step explanation:
Answer:
there were 63,000L of water initially in the pool
Step-by-step explanation:
do 900L times the first 20 minutes to find out how much water was drained during the first 20 minutes and you get 18,000L drained
then, add 18,000L plus the rest of the 45,000L of water drained from the pool to get 63,000L of water intially in the pool
Just plug in x = t
f(t) = 9 -2t.
We are given number 1,764.
And a factor tree of 1,764 is show in the diagram.
First 1764 is factored into 2 and 882.
Then 882 is factored to 2 and 441.
441 is factored to 9 and 49.
And finally 9 is factored to 3 and 3.
49 is factored to 7 and 7.
<em>So final factors we got 3 × 3 × 7 × 7.</em>
3 × 3 could be written as 3^2 and
7 × 7 = could be written as 7^2.
<h3>Therefore,

is the the simplest form.</h3>
