Answer:
18
Step-by-step explanation:
Important things to know:
“PEMDAS” is parenthesis, exponents, multiplication, division, addition, subtraction
equation: [tex]\frac{2(x^{2}+18) }{x}[/tex]
If x = 3, than
→ [tex]\frac{2((3)^{2}+18) }{3}[/tex]
after plugging in 3, we solve inside the parenthesis
3 to the power of 2 is 3 x 3 = 9
→ [tex]\frac{2(9 + 18)}{3}[/tex]
than you add the remaining things in the parenthesis where 9 + 18 = 27
→ [tex]\frac{2(27)}{3}[/tex]
multiply 27 by 2 = 54
→ [tex]\frac{54}{3} = 18[/tex]
divided 54 by 3 to get 18 as your final answer
