2 , 6 , 17 , 47 , <u>108</u> , ...
t(n) = 2n^3 - 8.5n^2 + 15.5n - 7
We can replace EF by 30 and get BC/30=10/3 and therefore BC=30×10 /3=10×10=100
The equivalent expression is 8t+32
Condensation reactions are anabolic, because in condensation reactions, two molecules come together to build new molecules.
Substitute into second equation:
x+3=2x-3
put variables on one side:
3x=6
x=2
Substitute to find y:
y=2+3
y=5
So (x, y) = (2, 5)
