Answer: I got 2/9 but im not sure if its right
Step-by-step explanation:
Answer:
=(a-b)(a^2+ab+b^2)
= a^3+a^2b+ab+ab^2-ba^2-ab^2-b^3
SIMPLIFY
=a^3+ab-b^3
Answer:
x ≤ 5
Step-by-step explanation:
2 -6/5 x ≥ -4
Subtract 2 from each side
2-2 -6/5 x ≥ -4-2
-6/5x ≥-6
Multiply by -5/6 on each side. Remember to flip the inequality since we are multiply by a negative
-5/6 * -6/5x≤-6(-5/6)
x ≤ 5

Answer:
positive
Step-by-step explanation:
To solve this, we can look at the unit circle (see attached photo), We know:
(0,1) = π/2
(-1, 0) = π
(0, -1) = 3π/2
(1, 0) = 0
Across the circle, we know that π/3 is between 0 and π/2. Therefore, as the unit circle line between that is positive in the x direction (cos), we can say that cos(π/3) is positive
