The functions f(x) and g(x) are defined below.

schepotkina [342]

For this case we have the following polynomials:
$f (x) = 21x ^ 2 + 13x - 20

g (x) = -3x - 4$
To divide the polynomials we must follow the following steps:
1) Same base, the exponents are added.
2) Only terms that have the same exponent can be added or subtracted.
3) If the remainder is zero, the division is exact.
Answer:
$f (x) / g (x) = -7x + 5
$
Note: see attached image for the solution.

You are enclosing a rectangular garden with 60 feet of ornamental fencing. the area of the garden is 200 square feet. what are t

Lilit [14]

The perimeter is equal to 60 feet and has the formula:

Perimeter = 2 l + 2 w

60 = 2 l + 2 w

The area is equal to 200 square feet and has the formula:

Area = l w

200 = l w

Rewriting area in terms of l:

l = 200 / w

Combining this with the perimeter formula:

60 = 2 (200 / w) + 2 w

60 = 400 / w + 2 w

Multiplying all by w:

60 w = 400 + 2 w^2

Dividing by 2 and rearranging:

w^2 – 30 w = - 200

Completing the square:

(w – 15)^2 = - 200 + (-15)^2

(w – 15)^2 = 25

w – 15 = ±5

w = 10, 20

Hence the dimensions of the garden is 10 feet by 20 feet
