Answer:
5
Step-by-step explanation:
20/4 is 5 (4 sides)
Answer:
not a function
Step-by-step explanation:
for example
In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.
For x2+y2=9
XXXXif (for example) x=0
XXXXthere are two values for y (namely +3 and −3) which satisfy the equation
and therefore the equation is not a function.

Answer:
x - 4
Step-by-step explanation:
The expression simplifies to ...

For x ≥ 4, the argument of the absolute value function is non-negative, so it remains unchanged. The simplified expression is ...
x - 4 . . . . for x ≥ 4
Answer:
x=square root 63. Basically the radical 63.
Step-by-step explanation:
So in the first triangle with the 3 in it. You have root 3 and use the a^2 +b^2=c^2 formula. So 3^2 + 3^2= x^2 and then when you solve you get radical 18^2 which is equal to radical 18 or square root 18. Then we go to the bigger triangle and we do the same formula but this time we have the c value which is 9. So we do radical 18^2 + x^2 = 9^2 and then solve that and minus 18 from the 81 since the radical goes off the 18 and you get square root63.
