f(x) = x + 3
when x = 0, f(x) = 3
when x = 1, f(x) = 1 + 3 = 4
when x = 2, f(x) = 2 + 3 = 5
when x = 3, f(x) = 3 + 3 = 6
answer is D
f(x) = x + 3
Since 6 are birds and you know he has 2 parakeets, you know he has 4 canarys. He has 5 goldfish since he has one less canary then goldfish. He has 1 turtle since he has 4 more goldfish than turtles.
2 parakeets + 4 canarys + 5 goldfish + 1 turtle = 12 pets

5 years.
Take the rent (14,400) and add 2.5% (0.025) of it (14400) for five (5) years.
Answer:
L=21.6in and w=13.6
Step-by-step explanation:
If the length is 8 inches longer than its width, we can write the width as "w" and the length as the width w+ 8
Area is (width)(Length) = (width)(width+8)
W
----------

| |
| | L = w+8

-----------
A = (w+8)(w)
A = w2 + 8w = 295.
(Problem states that area is 295 sq in)
Need to solve this quadratic equation
w2 +8y - 295 = 0
Factor:
(w - 13.64) (w + 21.64) = 0
So
w - 13.64 = 0. or. w + 21.64= 0
Solve these and get
w = 13.64. or. w = -21.64
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 13.64 inches
Length = 21.64 inches
