Can you please help me out guys It's factorisation

( 1 ) 6x² + 17x + 12

( 2 ) 12x² - 56x + 9

( 3 ) 18x² - 9x - 20

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

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

you would need to also lose 1 point for each of the other outcomes for it to be fair.
