Answer:

2.  A=D

Step-by-step explanation:

This is because the relation with AED - ACB is that they make a scalene triangle, by saying A=D proves the base exists at A=D, as we compare the sides at AED and ACB.

2 x length + 2 x width = perimeter.

2(2s-5) + 2(4s-13) = 108

Simplify:

4s-10 + 8s-26 = 108

Combine like terms:

12s - 36 = 108

Add 36 to both sides:

12s = 144

Divide both sides by 12:

s = 144/12

s = 12

Now replace s with 12 in each equation:

2(12) - 5 = 24-5 = 19

4(12) - 13 = 48-13 = 35

The answer is d. 35,35, 19,19

What is the equation of a circle with center (−8, 3) and radius 8?
Genrish500 [490]

Answer:

x^2 + y^2 + 16x + 6y + 9 = 0

Step-by-step explanation:

Using the formula for equation of a circle

(x - a)^2 + (y + b)^2 = r^2

(a, b) - the center

r - radius of the circle

Inserting the values given in the question

(-8,3) and r = 8

a - -8

b - 3

r - 8

[ x -(-8)]^2 + (y+3)^2 = 8^2

(x + 8)^2 + (y + 3)^2 = 8^2

Solving the brackets

( x + 8)(x + 8) + (y +3)(y+3) = 64

x^2 + 16x + 64 + y^2 + 6y + 9 = 64

Rearranging algebrally,.

x^2 + y^2 + 16x + 6y + 9+64 - 64 = 0

Bringing in 64, thereby changing the + sign to -

Therefore, the equation of the circle =

x^2 + y^2 + 16x + 6y + 9 = 0
