T(3t + 4) + 3t (3t+2t)

3t square+4t+9t square+6t square

9t square+6t square+3t square+4t

18t square+4t

Hey there!

t(3t + 4) + 3t(3t + 2t)

= 1t(3t + 4) + 3t(3t + 2t)

= 1t(3t) + 1t(4) + 3t(3t) + 3t(2t)

= 3t^2 + 4t + 9t^2 + 6t^2

= 12t^2 + 6t^2 + 4t

= 18t^2 + 4t

Therefore, your answer is: 18t^2 + 4t

Good luck on your assignment and enjoy your day!
