The question is:

Evaluate 6t−20−32u when t=6 and u=1/4

8

Step-by-step explanation:

The given expression is:

We need to evaluate the expression for the given values of t and u. Substituting t=6 and u=1/4 in the above expression we get:

Thus, the give expression is equal to 8 for t=6 and u=1/4

if x = 1, then the answer is 3.5
