Answer:

18m³ + 2m² – m

Combine (add and subtract) the terms that have the same variable and exponent. Do not combine terms that have different exponents or variables.

5m³ +5m³ + 8m³ = 18m³

3m² +3m² –4m² = 2m²

–2m –2m +3m = –m

Answer:

38

f(-9) is the value of f(x) when x = -9. Therefore, f(-9) = 4 from the graph. Doing the same with g(6), we can see that g(6) = 6. Our expression becomes:

-1 * 4 + 7 * 6

= -4 + 42

= 38
