Step-by-step explanation: To add these polynomials,

we simply add (-3x + 6) + (7x - 8).

Notice that I used parenthses around the polynomials.

This is a good habit to get into even though

the parenthses will not affect the addition.

Next, we simply add the like terms.

-3x + 7x is 4x and 6 + -8 is -2 so we have 4x + -2 or 4x - 2.

Ilya [14]
For this case what we must do is define h (x), which is given by:
 h (x) = f (x) * g (x)
 Where,
 f (x) = 5 (The number of fish breeding farms)
 g (x) = 80 (1.04) ^ x (The approximate number of fish per breeding farm)
 Substituting we have:
 h (x) = (5) * (80 (1.04) ^ x)
 Rewriting we have:
 h (x) = 400 (1.04) ^ x
 Answer:
 
the approximate population of the fish across all Mr. Dawson's farms after x months is:
 
h (x) = 400 (1.04) ^ x
