∆abc is similar to ∆pqr. corresponds to , and corresponds to . if the length of is 9 units, the length of is 12 units, the length of is 6 units, and the length of is 3 units, then the length of is units and the length of is units. nextreset

QR=4 and RP=2

As ΔABC≈ΔPQR and AB corresponds to PQ and BC corresponds to QR,

AB/PQ=BC/QR=CA/RP

Hence 9/3=12/QR=6/RP

i.e. 9/3=12/QR

or QR=3×12/9=36/9=4

and 9/3=6/RP

or RP=3×6/9=18/9=2

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
