Answer:
-77k²m³
Step-by-step explanation:
The variable arrangement is the same for each term, so we simply combine their coefficients:
k²m³ +22k²m³ -100k²m³ = (1 +22 -100)k²m³ = -77k²m³
companies often win in a credit transaction, due to their clients continually pay them for their usage.

Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
