Answer: x^3 - 1 = (x - 1)(x^2 + x + 1)
Explanation:
This is a type of factorizing called the sum or difference of 2 cubes:
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
The sum of the cubes is factored as:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we have: x^3 - 1 so follow the rule above.
x^3 - 1 = (x - 1)(x^2 + x + 1)
30÷25=1.2
she reads 1 page in 1.2 seconds
there fore 1.2×200=240
the answer is 240 seconds
Answer:
Neither
Step-by-step explanation:
Neither because sometimes as x increases, y increases and sometimes as x increases, y decreases so this graph have no corrleation so it neither.
X - 1 < = 6
x < = 6 + 1
x < = 7.....2nd number line is correct
