The first graph... it is the closest to it and shows the right answers.
Basically divide it by four.
2.5x-5 I'm pretty sure. Let me know if I'm wrong.
9x² - 16 = (3x - 4) (3x + 4)
A C
The value of ac together is 16(9x²) or 144x²
The value of B is zero, since there is no B (b is x, (note not x², but only 1 x))
hope this helps
Part c=t, part a=h,t
I'm sorry.but I'm not sure of part b
