Which option shows the equation for the line in the graph

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
