Answer:

Step-by-step explanation:

Begin by removing the brackets

4x + 5(-4x - b) = -16x - 5b

-(x - 2) = -x + 2

Add the two binomials together to get the third one

4x -20x - 5b - x + 2 = -17x - 8 Combine the like terms on both sides

-17x - 5b +2 = -17x - 8 Add 17x to both sides

-5b + 2 = - 8 Subtract 2 from both sides

-5b +2 -2 =- 8 -2 Combine

-5b = - 10 Divide by -5

b = -10/-5

b = 2

Answer:

$\textbf{J. }\dfrac{1}{x^2-x}$

Step-by-step explanation:

Factor the denominator and cancel the common factor.

$\dfrac{x+1}{x^3-x}=\dfrac{x+1}{x(x^2-1)}=\dfrac{x+1}{x(x-1)(x+1)}=\dfrac{1}{x(x-1)}\\\\=\boxed{\dfrac{1}{x^2-x}}$

MatroZZZ [7]

Answer:

$\large\boxed{\sin\dfrac{2\pi}{3}=\dfrac{\sqrt3}{2}}$

Step-by-step explanation:

$\sin\dfrac{2\pi}{3}=\sin\bigg(\pi-\dfrac{\pi}{3}\bigg)\\\\\text{use}\ \sin(x-y)=\sin x\cos y-\sin y\cos x\\\\=\sin\pi\cos\dfrac{\pi}{3}-\sin\dfrac{\pi}{3}\cos\pi\\\\\text{use the table from the attachment}\\\\\sin\pi=0\\\\\cos\dfrac{\pi}{3}=\dfrac{1}{2}\\\\\sin\dfrac{\pi}{3}=\dfrac{\sqrt3}{2}\\\\\cod\pi=-1\\\\\text{subtitute:}\\\\=(0)\left(\dfrac{1}{2}\right)-\left(\dfrac{\sqrt3}{2}\right)(-1)=\dfrac{\sqrt3}{2}$
