we have

<u>Find the greatest common factor GCF</u>
we know that

so
The GCF is equal to 
therefore

<u>the answer is</u>
The number is 
Answer:
Y = negative x + 9
Step-by-step explanation:
Find the equation of the line for side S-
m= 4-1/1-4 = 3/-3 = -1
<u>The Gradient is -1</u>
Since parallel lines share the same gradient, it should be either of the first two options.
We can see side Q shares the same gradient: 3-6/6-3= -1
Find the equation of the line of side Q-
y-y1= m(x-x1)
y-6= -1(x-3)
y-6=-x+3
<u>y= -x+9</u>
Answer: B
Step-by-step explanation:
The only labeled angle is 111
We can conclude that angle 3 is also 111
1 and 2 are both less than 90
Therefore, 1 is 69, 2 is 69, and 3 is 111
