Answer:
1. -8x² - 16x - 6      a = -8, b = -16, c = -6
1. 4x² - 1                  a = 4, b = 0, c = -1
Step-by-step explanation:
use the 'foil' method:
(4x + 2)(-2x - 3)
F: -8x²     O: -12x       I: -4x       L: -6
-8x² - 16x - 6
(2x + 1)(2x - 1)
F: 4x²     O: -2x       I: 2x       L: -1
4x² - 1

Answer:
height = 11.5 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated using the formula
A =  h(a + b)
 h(a + b)
where h is the height and a, b the bases
here a = 21, b = 8 and A = 166.75, hence
 h(21 + 8) = 166.75
 h(21 + 8) = 166.75
Multiply both sides by 2 to eliminate the fraction
29h = 333.5 ( divide both sides by 29 )
h = 11.5 in
