Final answer:
To find the value of the expression (t³ -35t²)/(-4t-8) when t=12, substitute t=12 into the expression and evaluate. The value is approximately 59.1.
Explanation:
To find the value of the expression (t³ -35t²)/(-4t-8) when t=12, substitute t=12 into the expression and evaluate.
(12³ - 35(12)²)/(-4(12) - 8) = (1728 - 5040)/(-48 - 8)
= -3312/-56 = 59.1
Therefore, the value of the expression when t=12 is approximately 59.1.
