Answer:
f(x) = x⁴-6x³-13x²+66x+72
Step-by-step explanation:
Factors are: (x+3)(x+1)(x-4)(x-6)
[(x+3)(x+1)][(x-4)(x-6)]
[x²+3x+x+3][x²-4x-6x+24]
(x²+4x+3)(x²-10x+24)
x⁴+4x³+3x²-10x³-40x²-30x+24x²+96x+72
f(x) = x⁴-6x³-13x²+66x+72
Step-by-step explanation:
1)
2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =
= 2 13/100
2)
2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =
= 713/100 = 7 13/100
3)
2.1 + 00.3 = 2.4
or did you mean + 100.3 ? then is is 102.4
4)
24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50
5)
3 24/100 + 8 7/10 =
= 300/100 + 24/100 + 800/100 + 70/100 =
= 1194/100 = 11 94/100 = 11 47/50
Answer:
C. 
Step-by-step explanation:
Let x represent number of miles.
We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.
The cost of riding x miles would be 
and the total cost of riding x miles would be 
.
Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.
We can represent this information in an inequality as:
Therefore, option C is the correct choice.
