Answer:

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally.

The numbers 500 and 300 are compatible for addition, since the sum of 800 can be easily calculated mentally.

Let f(x) = –4x and g(x) = 5x2. Andrew finds the composition [f o g](x) as shown below. What error did Andrew make? = 5(–4x)2 = 5
