3(16t^2 + 40t + 25) - 4

48t^2 + 120t + 75 - 4

48t²+71

Step-by-step explanation:

3(4t+5)²-4              Problem:

3(16t²+25)-4          In order of PEMDAS, Solve the exponent.

                                4t(4t) = 16t²            5(5) = 25

48t²+75-4            Distributive property

48t²+71               Subtraction property of equality
