Step-by-step explanation:

(x - 1)(x + 2) < 18

x^2 + x - 2 < 18

x^2 + x - 20 < 0

(x - 4)(x + 5) < 0

Hence, -5 < x < 4.

OLga [1]

Data:
B (Larger base) = 28 m
b (Minor base) = 18 m
h (height) = ?
A (area) = 475 m²

Formula:
$A = \frac{(B+b)*h}{2}$

Substitute:
$475 = \frac{(28+18)*h}{2}$
$475 = \frac{\diagup\!\!\!\!\!46^{23}*h}{\diagup\!\!\!\!2^1}\:\:\to\:\:\:475 = 23*h\:\:or\:\:\boxed{\boxed{23h = 475}}$

Answer:
$\textcircled{ A } 23h = 475$
