Answer:
Perpendicular because the slopes are opposite reciprocals
Step-by-step explanation:
Put parentheses around the '6 + 12 ÷ 6' and another parentheses around the '6 + 12':-
8 x 5 - ((6 + 12) ÷ 6)
= 40 - (18 ÷ 6)
= 40 - 3
= 37
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)
