I'm not sure if you meant to write 3x or [tex]x^{3}[/tex] instead of x3 but I will work out both versions just in case
In the equation 3x + 4 plug 6 in for x
3(6) + 4
Multiply 3 and 6 first
18 + 4
Add 18 and 4
22
OR
In the equation [tex]x^{3}[/tex] + 4 plug 6 in for x
[tex]6^{3}[/tex] + 4
Solve the exponent
(6*6*6) + 4
216 + 4
Add the numbers together
220
Hope this helped!
Answer:
220
Step-by-step explanation:
Im going to assume x3 equals x^3, so 6^3 is 216, add this to 4 and get 220
