Answer:

Step-by-step explanation:

All we can do here is combine like terms (add those that have the same the same exponent)

Good luck!
3a + 3b, for a=2 and b=4 ... The first thing you'd do would be to plug the numbers in -
3 x 2 + 3 x 4
Then multiply them -
6 + 12
Then add -
18.
So your answer should be 18.
That equation just equals ln(e^(-4/3)) which can be simplified to -4/3 because ln and e cancel each other out only leaving the power
It helps you know what to multiply and the product when you subtracting and adding fractions.
Answer:
The quantity of water drain after x min is 50
Step-by-step explanation:
Given as :
Total capacity of rain barrel = 50 gallon
The rate of drain = 10 gallon per minutes
Let The quantity of water drain after x min = y
Now, according to question
The quantity of water drain after x min = Initial quantity of water × 
I.e The quantity of water drain after x min = 50 gallon × 
or, The quantity of water drain after x min = 50 gallon × 
Hence the quantity of water drain after x min is 50
