Answer:
t+20=60 t=40
Step-by-step explanation:
t+20=60 subtract 20 from both sides
t=60-20 simplify
t=40
leading coefficient is 1
degree is 9
6x^3 - 2x^2 -11x +4
(3x-4)(2x^2+2x-1)
Multiply 3x by the second term
3x* (2x^2+2x-1)
6x^3 +6x^2 -3x
Multiply -4 by the second term
-4*(2x^2+2x-1)
-8x^2 -8x+4
Add these together, lining up the terms
