What is the solution set of the quadratic inequality 4(x + 2)^2 ≤ 0?
{x|x=-2}
{x|x€ R}
{x| x= 2}
0
PLEASE HELP

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

0.038
