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

Divide 8x2 + x2 +32x+4 by x2 +4.

Len [333]

Answer:

$\frac{8 {x}^{3} + {x}^{2} + 32x + 4}{ {x}^{2} + 4 } = 8x + 1$

Step-by-step explanation:

Assuming, we the given polynomial is

$8 {x}^{3} + {x}^{2} + 32x + 4$

and the divisor is

${x}^{2} + 4$

Then , the polynomial division is shown in the attachment.

This implies that:

$\frac{8 {x}^{3} + {x}^{2} + 32x + 4}{ {x}^{2} + 4 } = 8x + 1$
