Answer:

Step-by-step explanation:

2x^2-4x 6x^2-5x

2x^2 times 6x^2= 12x^4

2x^2 times -5x= -10x^3

-4x times 6x^2= -24x^3

-4x times -5x= 20x^2

12x^4-10x^3-24x^3+20x^2

12x^4-34x^3+20x^2

option B

Cos theta is positive and sin theta is negative in quadrant IV

$Cos \ \theta =\dfrac{4}{5}=\dfrac{adjacent \ side}{hypotenuse}$

We have to find opposite side using Pythagorean theorem.

x² + 4² = 5²

x² + 16 = 25

x² = 25- 16

x² = 9

$\sf x =\sqrt{9}\\\\x = 3$

$\sf \ sin \ \theta =\dfrac{opposite \ side}{hypotenuse}\\Sin \ \theta =\dfrac{-3}{5}$
