Answer:

AB = 32

Step-by-step explanation:

Since line l bisects AB at point M, we have AM = MB.

$4x = 5x - 4$

$4x + 4 = 5x$

$x = 4$

AM = 4(4) = 16, MB = 5(4) - 4 = 16.

So AB = AM + MB = 16 + 16 = 32.

Is it right

Rasek [7]

F(t) = t2 + 4t − 14

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

<span>the axis of symmetry is y = -18</span>
