Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D
Pemdas stands for parentheses, exponents,multiplication,division,addition, and subtraction. that is the order you need to expand this
The price of the truck is 4500 dollars.
But he paid it into breakdown:
=> 1500 dollars first payment
=> 350 dollars = 10 months => 350 * 10 = 3500 dollars
=> Total = 3500 + 1500 = 5000 dollars
=> 5000 - 4500 = 500 dollars additional for 10 months
=> 500 / 10 = 50 dollars per month
=> 50 * 12 = 600 dollars for 1 year
=> 600 / 4500 = 13.33% of the yearly interest.
If you're looking for the reading of the ammeter, it should read the sum of the currents, namely 8+4=12 amps, assuming nothing else is drawing a major current.
