The equation of a given circle in general form is x^2+y^2-8x+12y+27=0. Write the equation in standard form, (x-h)^2+(y-k)^2=r^2,

umka2103 [35]

Answer:

(x - 4)² + (y + 6)² = 5²

Step-by-step explanation:

rearrange the general equation as follows

collect the terms in x and y together and place the constant on the right side

x² - 8x + y² + 12y = - 27

add (half the coefficient of the x/y term)² to both sides

x² + 2(- 4)x + y² + 2(6)y = - 27

(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36

(x - 4)² + (y + 6)² = 25

(x - 4)² + (y + 6)² = 5² ← in standard form

Dale and sharon mahnke have decided to fence off the garden plot behind their house, using their house as a "fence" along one

kkurt [141]

The length l is given as:

l = 2 w – 6

where w is the width

We know that the fencing is 30 feet therefore the perimeter (excluding the side of the house) is:

P = l + 2 w = 30

2 w – 6 + 2 w = 30

4 w – 6 = 30

w = 9

So the length l is:

l = 2 (9) – 6

l = 12

<span>The dimensions are 12 ft x 9 ft</span>

I got 13.7 is that correct

Ghella [55]

Answer:

The answer to your question is 10.5 in

Step-by-step explanation:

Data

First triangle

height = x

base = 7 in

Second triangle

height = 12 in

base = 8 in

Process

1.- Use proportions to solve this problem, relates the sides of a triangle with the same sides of the other triangle.

$\frac{x}{7} = \frac{12}{8}$

2.- Multiply both sides by 7

$7\frac{x}{7} = \frac{7(12)}{8}$

3.- Simplify

x = $\frac{84}{8}$

4.- Result

x = 10.5 in
