There's a t & s (t = 6x by 8)(s = 4x-1 by 5) area of t is 10 greater than s. find x - ANSWER S = 5(4x-
1)=>(20x-5) & T = 1/2 x 8 x 6x =(24x) ==> T=24x-10) & (S=20x-5) => 24x-20x / 10-5 ==> 4x=5 & [x=1.25]

Here's first 4 terms of quadratic sequence. (3,9,17,27) Find expression in terms of n for nth term - ANSWER Diff between: (9&3=6)(17&9=8)(27&17=10) so => Diff between: (8&6=2)(10&8=2) {formula: an^2+bn+c} => (3)>a(1)^2+b(1)+c & (9)>a(2)^2+b(2)+c & (17)>a(3)^2+b(3)+c so (a=1)(b=3)(c=-1) [n^2+3n-1]
