Answer
Find out the how much fluid do i have to drink .
To prove
As given
I.e
Thus
L.C.M of (4,5) = 20
Simplify the above
.
In the decimal form
Therefore the total fulid i have to drink is 10.7 .
so 5 people work each one for 21 minutes, that means 21+21+21+21+21 minutes altogether, namely 105 minutes, it took that long for 7 walls, hmmmm how long for just one wall then? well, 105 ÷ 7, namely 15 minutes then, for just 1 wall.
now, if it takes 15 minutes of work to do one wall, what about 5 walls? well, that'd be 15*5 or 75 minutes.
so if we have 3 folks working, how much would each one work? well, 75 ÷ 3, namely 25 minutes, so each of them will work 25 minutes, namely 25+25+25 minutes, so in 25 minutes, they'll be done with 5 walls.
Well, it depends on the school. Do you have a list of the classes?
X^2-7x+12 because when you distribute its
X*X +
(X*-4)+(x*-3) +
-3*-4
