Answer:
B
Step-by-step explanation:
A square has 2 pairs of parallel line because all four sides are equal
Answer: 19 cm
<u>Step-by-step explanation:</u>

99 = 
99 = 
198 = (2x + 13)(x - 4)
198 = 2x² + 5x - 52
0 = 2x² + 5x - 250
0 = 2x²- 20x + 25x - 250
0 = 2x(x - 10) + 25( x - 10)
0 = (2x + 25)(x - 10)
0 = 2x + 25 or 0 = x - 10
= x or x = 10
Since length cannot be negative,
can be disregarded
Larger base: x + 9 = 10 + 9 = 19
There are two real roots (5 and -5) and 4 imaginary roots
