Which of these equations has no real solution? A) -4(2x + 1) = -8x - 2
B) 3x-13 = 7(x + 2) - 4(x - 7)
C) -5 - 9x = 3(1 - 3x) - 8
D) 8(5x - 3) = 6(-3X -4)

A

Step-by-step explanation:

A) -4(2x+1)=-8x-2,    

-4*2x=-8x  

-4*1=-4,  

-8x-4=-8x-2

-4=0x-2

-2=0x

-2 IS NOT =0

Hope this helps

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
