Answer:
Total cost = $(x⁴ + 12x³ - 45x²)
Step-by-step explanation:
It is given that a state department of public safety added (1/3)x² + 5x miles of highway to connect CoolTown and Bragville.
So, length of highway; L = (1/3)x² + 5x miles
Cost of highway; C = $3x² - 9x per mile
Thus, total cost = LC
Total cost = ((1/3)x² + 5x) x (3x² - 9x)
Total cost = x⁴ - 3x³ + 15x³ - 45x²
Total cost = $ x⁴ + 12x³ - 45x²
Bank D is the correct answer. He will always have sufficient funds,so by leaving out that column Bank D is the least expensive.
Answer:
2x-10
Step-by-step explanation:
Multiply BOTH x and -5 by 2
Answer:
-x^7
Step-by-step explanation:
g(x) =f(x) +3
given f(x) =3x
i.e. g(x) =3x+3
For F(x) to be same as g(x)
3 must be added to f(x)
i.e. h(x) =3x+3
->h(x)= 3x +3(1)
-> h(x) = f(x) +f(1)
-> h(x) =f(x+1)
Hence Option (a) is your answer...
Hope it helps...
