Answer:
a 3 + b 3 = (a + b) (a 2 − a b + b 2 ). Substituting a = x and b = 3 into the formula yields: x 3 + 27 = (x + 3) (x 2 − 3 x + 9).
Step-by-step explanation:
A dotted line is not included in the solution so there is no equal sign.
The blue area is to the right of the dotted line so the solution is >
The line crosses the x axis at -2
The answer is : x-y > -2
