Please help with #7!!!
ioda

Answer:

44

Step-by-step explanation:

Given a polynomial f(x) divided by (x + h) then the remainder is f(- h)

Here f(x) is divided by (x + 4), thus remainder is calculated as

f(- 4) = (- 4)³ + 5(- 4)² - 7(- 4)

       = - 64 + 5(16) + 28

       = - 64 + 80 + 28 = 44 ← Remainder
