Answer:
12s^2 - s - 20
Step-by-step explanation:
It's simplest form is when it's fully expanded.
To expand: (3s-4)(4s+5)
(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)
= 12s^2 + 15s -16s -20
= 12s^2 - s - 20
So lets solve this!
Quarts of water 1st container holds= 17/8
Quarts of water 2nd container holds= 5 3/4
Quarts of water does the second container holds than the first container=?
First of all we need to change 5 3/4 into an improper fraction
5 3/4= 23/4
Secondly, we need to find the LCM of 17/8 and 23/4
LCM:
17/8= 51/24
23/4= 138/24
So now we have got both of the LCM's
Quarts of second container holds the first container= 23/4 - 138/24=87/24
Your answer is 87/24
Hope this Helps!
