Answer:
(d) (-2, 6)
Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex

<em>Additional comment</em>
The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
Answer:
38 stamps of each
Step-by-step explanation:
0 .48 + 0.05 = 0.53
20.14 / 0.53 = 38
verification
0.48 x 38 = 18.24
0.05 x 38 = 1.9
18.24 + 1.9 = 20.14
Answer:
18 cubic feet
Step-by-step explanation:
Cut the figure up.
9+6+3=18
18ft^3
You will need to add all of the hours and multiple by 8.60 that is going to give you the total of =202.1
Since all of these numbers have the same variable they can all be added up to get a sum of 10a which is its simplified form.
