Answer:
in the steps
Step-by-step explanation:
do 432*8 then just add a 0
The answer would be (A) 6
It would be 70% of 400
490(.7) = 280
What we want to do here is make it long division. x²+2x+8 on the left, and
+x³+7x²-6x+8 on the right, as will be shown
x²
________________________________________
x²+2x+8|
+x³+7x²-6x+8
We start off by dividing
by x², which is x². After that, we put x² at the top and subtract (x²+2x+8)*(x²) from the whole equation, which looks like
x²
________________________________________
x²+2x+8|
+x³+7x²-6x+8
- (
+2x³+8x²)
_____________________
-x³-x²-6x+8. Continue this pattern until you can't (the next step would be dividing (-x³ by x²) and you should have your answer! Good luck, and feel free to ask any questions as necessary!
