A well-known formula gives us that

. Additionally, the sum of the angles in a circle is 360, so

, so

. Therefore,

.
Answer:
The firston one is a scale factor of two and the second one is a scale factor of three.
Step-by-step explanation:
You just look at the coordinates. (1,1):(2,2) and (4,0):(8,0) and then for the second one (-1,0):(-3,0) and (3,2):(9,6).
1x2=2
4x2=8
-1x3=-3
3x3=9
2x3=6
The answer is x=2/3!! Hope this helped
Answer:
(x+5)^2 = 1
Step-by-step explanation:
x^2+10x+24 = 0
Subtract 24 from each side
x^2+10x+24 -24 = 0-24
x^2+10x = -24
Take the coefficient of x
10
Divide by 2
10/2 =5
Square it
5^2 = 25
Add it to each side
x^2+10x+25 = -24+25
Take the coefficient divided by 2 inside the factor
(x+10/2) ^2 = -24+25
(x+5)^2 = 1
