Answer:
x3 over 64+3x^ over 8+3x+8
Step-by-step explanation:
Answer:
x ≈ 11.23
Step-by-step explanation:
Given
tan24° = 
( multiply both sides by x )
x × tan24° = 5 ( divide both sides by tan24° )
x = 
≈ 11.23 ( to 2 dec. places )
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!
