Answer:
The factors of 20 is 1, 2, 4, 5, 10, 20
The factors of 16 is 1, 2, 4, 8, 16
Step-by-step explanation:
The set of factors of 20 is {1, 2, 4, 5, 10, 20} and the set of factors of 16 is {1, 2, 4, 8, 16}. {1, 2, 4, 5, 10, 20} ∩ {1, 2, 4, 8, 16} = {1, 2, 4} which has greatest value 4. So, GCF(20, 16) = 4.

X^2= AB^2 + BC^2
X^2= 8^2 + 10^2
X^2= 64+100
X^2= 164
X= 12.80
x= -1/3
y= -3 1/3
Make both of them into y=Mx+b form
y=-x-3
y=(-x-7)/2
Substitute the x-3 in the first equation for the y in the second one.
x-3=(-x-7)/2
2x-6=-x-7
3x=-1
x=-1/3
Now that we have x, we can solve for y.
y=-1/3-3
y=-3 1/3
