Answer:

I assume AC = 49.89 since the number is cut off

Step-by-step explanation:

tangent(degree) = opposite / adjacent

To find AC, you can set up tan(29) = AC / CB

tan(29) = AC / 90 (the picture is cutted off, so I assume....)

$90*tan(29)$ = AC

murzikaleks [220]

Answer:

 $- 48 {x}^{6} + 16 {x}^{5} - 20 {x}^{2}$ 

Option D is the correct option.

Solution,

 $- 4 {x}^{2} (12 {x}^{4} - 4 {x}^{3} + 5) \\ = - 4 {x}^{2} \times 12 {x}^{4} + 4 {x}^{2} \times 4 {x}^{3} - 4 {x}^{2} \times 5 \\ = - 48 {x}^{6} + 16 {x}^{5} - 20 {x}^{2}$ 

hope this helps...

Good luck on your assignment...
