True.
Since

,

and the solutions are decreasing functions.
Answer:
AB = 14
DE =7
Step-by-step explanation:
Remark
<em>AB</em>
Opposite sides of a parallelogram are equal.
AB = CD
AB = 14
<em>DE</em>
According to the diagram AE = 19
AD = 26 which is the same size as BC
DE = 26 - 19 = 7
DE = 7
The only that has the shape of the one below.
y = -4(x^3 + 7x^2+8x - 16)
Let x = 1
y = - 4(1 + 7 + 8 - 16)
y = 0
y = -4(x -1)(x^2 + 8x + 16)
y = -4(x - 1)(x + 4)^2
