Answer:
x = 2/3 or 0.666...
Step-by-step explanation:
-3 + 1 + 10x = x + 4
-2 + 10x = x + 4
10x = x + 4 + 2
10x = x + 6
10x - x = 6
9x = 6
x = 6/9
x = 2/3 or 0.666...
First, you would go;
12÷2=6
Then, you would do;
12+6+24= 42
Finally;
60-42 = 18
John needs $18 to buy the hockey stick.
The correct answer is option D which is the function is even because of its symmetry about the y-axis.
<h3>What is even function?</h3>
The function which remains unchanged when the negative value of the variable is filled in the function is called an even function and this function is symmetric about the y-axis.
Given function:-
f(x) = 3x⁴+2x²
Now put the value x = -x in the function
f(-x) = 3( -x⁴)+2(-x²)
f(-x) = 3x⁴ + 2x²
f(-x) = f(x)
here we can see that when we put the value of negative x the function remains unchanged.
Therefore the correct answer is option D which is the function is even because of its symmetry about the y-axis.

Answer: The volume is 288π .
Step-by-step explanation:
V= 4/3 *n*r^3
V = 4/3*n * 6^3
v=4/3 *n * 216
v= 288n
