Good evening Gloria

3t(t+2)-3t² for t=19

Well the first thing we need to do is to replace 19 everywhere we see T

So let's do it together

3(19)(19+2)-3(19)²

57(21)-3(361)

1197-1083

= 114

I hope that's help and if you have questions please let me know :)


Please give my answer a Thanks and stars ↓
