Naddik [55]

Answer:

$=8\left(2a+9\right)$

Step-by-step explanation:

$16a+72$

$\mathrm{Rewrite\:}16\mathrm{\:as\:}8\cdot \:2$

$\mathrm{Rewrite\:}72\mathrm{\:as\:}8\cdot \:9$

$=8\cdot \:2a+8\cdot \:9$

$\mathrm{Factor\:out\:common\:term\:}8$

$=8\left(2a+9\right)$

Hence, the correct answer is $=8\left(2a+9\right)$
