Answer:
Take the square root of the constant (number w/o the variable) and then multiply that by 2.
Step-by-step explanation:
A perfect square trinomial is something like this: 
If I have 6x, and I want to find the last term I would take half a six and then square it to get 9.
SO.... To get the middle term of a perfect square trinomial, you would need to do the reverse.. So...
1) Take the square root of the constant...
2) Multiply that by 2

3 dumplings can be made by Serenity
<em><u>Solution:</u></em>
Given that,
Serenity has 
cups of dough to make dumplings
She uses 
cup of dough for each dumpling
To find: Number of whole dumplings made
From given information,
To find the number of whole dumplings made, we can divide the total cups of dough by cups of dough for 1 dumpling
Thus 3 dumplings can be made
80 cups in a 5 gallon jug of water.
1 quart has 4 cups
1 gallon has 4 quarts
1 gallon = 4 quarts * 4 cups = 16 cups
5 gallons = has 80 cups of water.
(4 cups / 1 quart) x (4 quarts / 1 gallon) x (5 gallons) = 4 x 4 x 5 = 80 cups <u>
</u>
