Answer 2

Answer:

$question \: \: 16 -$

$\frac{5}{7} \: and \: \frac{6}{7}$

$\frac{5}{7} \times \frac{3}{3} = \frac{15}{21} \: \: and \: \: \frac{6}{7} \times \frac{3}{3} = \frac{18}{21}$

$\frac{16}{21} \: and \: \frac{17}{21}$

$question \: \: 17 -$

${6x}^{2} + 17x + 12$

${6x}^{2} + 9x + 8x + 12$

$3x(2x + 3) + 4(2x + 3)$

$(3x + 4)(2x + 3)$

$(3x + 4)(2x + 3) \: \: \: is \: \: your \: \: answer$
