You plug them into each other for x like so:
(3(radical sign)-4)^3+4
-4+4
You're left with x
Then do the same for the other one
3(radical sign)(x^3+4)-4
X+4-4
Left with x again there fore it is an inverse
Answer:
3)x=−9 and x=4
4)x=−12 and x=−5
5)x=8 and x=14
6)x=−7 and x=3

Answer:
x and y are 5.66 units
Step-by-step explanation:
The triangle above is a right angled triangle ; and can be solved using trigonometric relation :
Using :
Sin 45 = opposite / hypotenus
Opposite = y ; hypotenus = 8
Sin 45 = y/8
y = sin 45 * 8
y = 5.66 units
Side length x ;
Sin 45 = opposite / hypotenus
Sin 45 = x / 8
x = sin 45 * 8
x = 5.66 units
Answer (apply the FOIL method)
X^2+8x+15
Answer:
