8y - 11y + 6
Combine like terms
-3y + 6 is the simplified answer.
The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.
So, 3 x 8 = 24.
Then, to find out how much he saves each day, you would find how much he used before,
11 x 8 = 88
Next we want to see how much Nathan saved, so we subtract the total,
88 - 24 = 64
Nathan saved 64 gallons.
So you divide 12.00 by 0.75 and you get 16 which is the number of cookies he sold.
Writing it in the form of a+bi we get 0+4i
Step-by-step explanation:
We need to evaluate expression -16 squared and write the result in form a+bi
The given expression is: 
We know that 
We know that 16= 4x4 = 4^2
Putting values:

So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
