(3x^2 )(−2x^4 ) = 3(−2)x^2x4 =

Step-by-step explanation:

In exponents multiplication, if base is same, add the powers.

Okay so I will do it step by step

(3x^2 )(−2x^4 ) = 3(−2)x^2x4 = (-6)x^2

= -6x^6

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
