Question

Evaluate 11+(t²−6) when t=5.
a) 16
b) 26.6
c) 116
d) 30

Answer 1

To solve 11+(t²-6) when t=5, substitute 5 into the equation, resulting in 11+(5²-6), which simplifies to 30.

Step-by-step explanation:

To evaluate the expression 11+(t²-6) when t=5, you simply substitute the value of t into the equation and simplify:

1. Replace t with 5: 11+(5²-6).
2. Calculate 5²: 11+(25-6).
3. Simplify inside the parentheses: 11+(19).
4. Add 11 and 19: 30.

Therefore, the evaluation of the expression 11+(t²-6) when t=5 is 30.
