Answer:
h = 18.
z = 54.
Step-by-step explanation:
Form 2 equations:-
z = 3h ( because opposite angles in a parallelogram are equal)
z + 7h = 180 ( because inside angles add up to 189 degrees).
Substitute z = 3h in the second equation:
3h + 7h = 180
10h = 180, so h = 18.
Therefore z = 3h = 54.
f(x) = (x- zero) * (x -zero)
f(x) = (x--2) (x-8)
f(x) = (x+2) (x-8)
if you need it multiplied out
f(x) = x^2 +2x -8x-16
f(x) = x^2 -6x-16
