in the diagram, line ab is parallel to line cd. assume that b = 6x + 8 and that
zg = 4x + 12. find the value of x.

i agree because i see the other persons thinking is clear

c.)

step-by-step explanation:

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
