GEOMETRY 22 POINTS!

In the following diagram, the length of AB is 9 units, and the length of BD is 4 units. Find x, the length representing CV. Give your answer to one decimal place.

20.3 units

Step-by-step explanation:

AB/CB = BD/AB

9/CB = 4/9

CB = 9×9/4

CB = 81/4 = 20¼ units

20.25 (20.3 units correct to 1 dp)

step-by-step explanation:

the true ones are a b and d

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
