Answer:

- 2x - 31

Step-by-step explanation:

Given

- 3(4x + 5) - 2(- 5x + 8)

Multiply the terms in the first parenthesis by - 3 and the terms in the second parenthesis by - 2

= - 12x - 15 + 10x - 16 ← collect like terms

= (- 12x + 10x) + (- 15 - 16)

= - 2x - 31

Answer:

1 -√2

Step-by-step explanation:

$\tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}$

tan(7π/8) = 1 -√2
