George simplified the problem (-2x + 23x2 +11) – (5 – 9x® + x) in three steps below:
Problem: (–2x + 23x2 +11) – (5 – 9x3 + x)
Step 1: -2x + 23x2 + 11 – 5 – 9x² + x
Step 2: -923 + 23.02
2x + x + 11 - 5
Step 3: -923 + 23x2 – x + 6
What is George's error? Explain using specific examples from the problem.

-81 -56 -27 0 81

step-by-step explanation:

the answer is 1030 it's very simple math.

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
