Question 1: factor out the greatest
common factor
3t5s − 15t2s3
question 1 options:
3(t5s − 5t2s3)
3t2(t3s − 5s3)
3t2s(t3 − 5s2)
-12t3s2

For this case we have that by definition, the GCF or (Greatest Common Factor) is given by the greatest common factor that divides both terms without leaving a residue.

15: 1,3,5,15

3: 1.3

Then we have the GCF of the expression is:

Option C

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

$113.42

i hope that is right.
