Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Answer:
5/1
Step-by-step explanation:
Cause I say so. Rise/run is rate of change.
A 4th degree polynomial will have at most 3 extreme values. Since the degree is even, there will be one global extreme, with possible multiplicity. The remainder, if any, will be local extremes that may be coincident with each other and/or the global extreme.
(The number of extremes corresponds to the degree of the derivative, which is 1 less than the degree of the polynomial.)
Answer:
$500
Step-by-step explanation:
You hand him 100%
He pays back 140%(original amount plus 40%)= 700
Original amount =x
700/140 = x/100
140x=700*100
140x = 70,000
x=500
200 is the 40% of 500
500+200= 700
