Answer:
The GCF is going to be 20
Step-by-step explanation:
This Is how I find the GCF of 2 numbers. I find the prime factorization first, then I find the common factors and multiply them. Here
The prime factorization of 20, 2 × 2 × 5= 20
The prime factorization of 80, 2 × 2 × 2 × 2 × 5 = 80
The common factors are 2, 2, and 5. We multiply those to get the GCF.
2 × 2 × 5 = 20
15?im not sure...but I think thats right
X^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0
We have two factors:
(x - 5) and (x + 3)
Set each factor to 0 and solve for x.
Take it ftom here.
If the chords are equal , then the measurement of both the chords will also be the same . That means ,
