Answer:

solution,

Sum of exterior angle of polygon=360°

$3x - 5 + 2x + 10 + 90 = 360 \\ or \: 3x + 2x - 5 + 10 + 90 = 360 \\ or \: 5x + 5 + 90 = 360 \\ or \: 5x + 95 = 360 \\ or \: 5x = 360 - 95 \\ or \: 5x = 265 \\ or \: x = \frac{265}{5} \\ x = 53$

Hope this helps...

What's -8 + (-1 1/8)

gogolik [260]

I think the answer is 9.375 if it needs to be in decimal form. If it needs to be in fraction form it would be improper, 9 3/8 would be the fraction. Hope it helps!

F(x + h) – f(x)

olga nikolaevna [1]

Answer:

-6x² -6xh -2h²

Step-by-step explanation:

Apparently, you want ...

(f(x+h) -f(x))/h

for f(x) = 14 -2x³

That difference quotient is ...

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{(14 -2(x+h)^3)-(14-2x^3)}{h}\\\\ =\dfrac{14-2(x^2 +3x^2h+3xh^2+h^3)-14+2x^3}{h}=\dfrac{-6x^2h-6xh^2-2h^3}{h}\\\\ =\boxed{-6x^2 -6xh-2h^2}$
