COPYING IS NOT AT ALL GOOD MY BOY ! TRY TO CHANGE THAT HABIT

y = 2x^2 - 4

Add both side 4

y + 4 = 2x^2 - 4 + 4

y + 4 = 2x^2

Divide both sides by 2

( y + 4 ) ÷ 2 = 2x^2 ÷ 2

y + 4 / 2 = x^2

x^2 = y + 4 / 2

x = + √(y+4/2) Or x = - √(y+4/2)

Thus the second option is the correct answer.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
