Let's simplify step-by-step.
−x^3 + 5x + 7x^2 + 8x^3 − ( −x^3 + x )
Distribute the Negative Sign:
= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 + x )
= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 ) + −1x
= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x
Combine Like Terms:
= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x
= ( −x^3 + 8x^3 + x^3 ) + ( 7x^2 ) + ( 5x + −x )
= 8x^3 + 7x^2 + 4x
Answer:
= 8x^3 + 7x^2 + 4x

Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = 
and tan x = 
thus
+ tanΘ × cosΘ
= 
+ 
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
Answer:
3/5
Step-by-step explanation:
9/10 and 2/3 can cross cancel
3 goes into 9, 3 times
2 goes into 10, 5 times
they both go into themselves once
our new fractions are 3/5 and 1/1 which equals 3/5
