Answer:
Step-by-step explanation:
Triangles ADC and ACB are similar.
Therefore AC / AB = AD / AC
6 / AB = 4 / 6
4AB = 36
AB = 9 (answer).

Unfortunately I can't read your answer options properly. The copied text is just too messed up. But hopefully the step-by-step calculation will help you.
Lemme know if it worked for you and if you have further questions.
Step-by-step explanation:
3x - 2y = -6
can be rewritten as
2y = 3x + 6
or simpler
y = 1.5x + 3
we know that it's parallel to this line, but we don't know how much lower or higher the new line will be, so let's set "+3" as an unknown variable.
y = 1.5x + b
(the letter b is now what we try to solve for)
now let's plug in the x-/y-Informations of the given point
2 = 1.5 * 4 + b
2 = 6 + b
-4 = b
so the new line is
y = 1.5x -4
(the given point lies on that line and it's parallel to the other line)
let's multiply everything by two to get closer to the original format
2y = 3x -8
it could also be expressed as
2y = -(-3x+8)
(in hope that this may help for choosing an answer option)

Answer:
C. 3x^2 -13x + 7
Step-by-step explanation:
Lets start in the ones place:
+3
- (-4)
_______
+7
Now go to the tens place:
-5x
-(8x)
________
-13x
Lastly, go to the hundreds place:
6x^2
-(3x^2)
_________
3x^2
So, the correct answer is "3x^2 -13x + 7", which is C.
I hope this helps! :)
