Answer: 62
The expression given below
[tex]t^2\text{ - 12w / x}[/tex]Where t = 8, w = 1/2 and x = 3
To find the value of this expression, we need to substitute the value of t, w and x into the above expression
[tex]\begin{gathered} t^2\text{ - 12w / x} \\ (8)^2\text{ - 12(}\frac{1}{2})\text{ / 3} \\ (8)^2\text{ - }\frac{12}{2}\text{ / 3} \\ =\text{ 64 - 6/3} \\ =\text{ 64 - 2} \\ =\text{ 62} \end{gathered}[/tex]
