Find an expression which represents the difference when (x+4y)(x+4y) is subtracted from (-8x+3y)(−8x+3y) in simplest terms.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

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

answer:

c) the x-coordinate of the center of the circle increases by 3
