${ \tt{(x + 3)(x - 1)}} \\ = { \tt{ {x}^{2} - x + 3x - 3 }} \\ = { \tt{ {x}^{2} + 2x - 3 }} \\ \\ { \boxed{ \bf{coefficient = 2}}}$

$105 \: m$

Answer C is correct

Step-by-step explanation:

$d = \frac{w}{f} \\ = \frac{1.18 \times {10}^{6} }{1.12 \times {10}^{4} } \\ = 1.05 \times {10}^{6 - 4} \\ = 1.05 \times {10}^{2} \\ = 105m$

hope this helps
