Answer:
35-7x
Step-by-step explanation:
Multiply parenthesis by -7
Let's call he width of the notebook w and the length l
w*l=80
2(w+l)=36
w+l=18
w=18-l
(18-l)*l=80
-l^2+18*l-80=0
l=8 or 10
Therefore, the notebook is 8 by 10 inches
Answer:3x^2-5x=-8 is the one that has 2 complex solutions
Step-by-step explanation:
