F(x)= 0.018x, for 0≤x≤500
f(x)= (0.018×500) +0.056(x-500), for x>500
Answer:
(4a + 7b)(16a² - 28ab + 49b²)
Step-by-step explanation:
Use the sum of two cubes to factor
In addition
a³ + b³ = (a + b)(a² - ab + b²)
In subtraction
a³ - b³ = (a - b)(a² + ab + b²)
64a³ + 343b³ = (4a + 7b)(16a² - 28ab + 49b²)
They are in the ten thousandths and hundred thousandths place
The standard form is
-x + y = 19
