12: 1,2,3,4,6,12

9: 1,3,9

your answer would be 3.

That sounds about right to me. in order to find the Greatest Common Factor (GCF) look for the common factors that it has (:

First, write down all the factors for 9 and 12:
9) 1, 3, 9
12) 1, 2, 3, 4, 6, 12

The greatest number that both lists share is 3, so 3 is your GCF.

5. Find the equation of a circle whose center is at (5, -8) and radius 8.

Brums [2.3K]

Answer:

$x^{2} + y^{2} -10x -16y + 39$

Step-by-step explanation:-

The equation used to find the equation of circle is :-

$(x-a)^{2} + (y-b)^{2} = radius^{2}$

'a' means the x coordinate of the circle, 'b' means y coordinate of the circle.

In the question, it's given that the coordinates of the circle are (5, -8) and radius is 8cm.

So, 'a' will be 5 and 'b' will be -8

So,

$(x-5)^{2} + (y--8)^{2} = 8^{2}$

$(x-5)^{2} + (y+8)^{2} = 64$

$x^{2} - 10x + 25 + y^{2} - 16y + 64$

$x^{2} + y^{2} -10x -16y + 64 - 25$

= $x^{2} + y^{2} -10x -16y + 39$

Answer:

x=25

Step-by-step explanation:

4x-25=75

Add 25 to both sides

4x=100

Divide both sides by 4

x=25

x is equal to 25.
