Peter and jade are using what they know about properties to write an expression equivalent to 2×(n+6)+3. Whose answer makes sense? Whose answer is nonsense?

Peter's work
2×(n+6)+3
2×n+(6+3)
2xn+9
2n+9

Jade's work
2×(n+6)+3
(2×n)+(2×6)+3
2n+(12+3)
2n+15

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
