Answer:

$\boxed{ \bold{\sf{ { \boxed{ \sf{8 {x}^{5} + 4 {x}^{4} - 12 {x}^{2} }}}}}}$

Option C is the correct option.

Step-by-step explanation:

$\sf{4 {x}^{2} (2 {x}^{3} + {x}^{2} - 3})$

Distribute 4x through the parentheses.

$\dashrightarrow{ \sf{4 {x}^{2} \times \: 2 {x}^{3} + 4 {x}^{2} \times {x}^{2} - 4 {x}^{2} \times 3}}$

$\dashrightarrow{ \sf{8 {x}^{5} + 4 {x}^{4} - 12 {x}^{2} }}$

Hope I helped!

Best regards! :D

Let (-5,-4) be a point on the terminal side of (theta). Find the exact values of cos, csc, and tan.

Rasek [7]

The exact values of the trigonometric identities cos, csc and tan as required in the task content are; -√41/5, -√41/4 and 4/5 respectively.

<h3>What are the exact values of cos, csc and tan as required in the task content?</h3>

It follows from above that the terminal side of the angle theta as described is on the point with coordinates (-5, -4).

Hence, the points spans 5 units leftwards and r units downwards on x and y axis respectively.

Hence, the length of the line that describes the angle by Pythagoras theorem is;

h = √((-4)² + (-5)²)

h = √41.

Hence, it follows from trigonometric identities that;

Cos (theta) = -5/√41.

Csc (theta) = -√41/4

Tan (theta) = 4/5

steve=s

kevin=k

s=5

k=1

1=5=6

390 divided by 6 equals s 65

divide further by 5 which equals k 13
