Answer 2

1)common difference of an A. P. = T2 - T1 = -3 -1= -4
2) suppose two similar triangles are ABC and PQR
then ar of ABC/ ar of PQR = (4)^2 / (9)^2
= 16/ 81
3) see the attachment 180-130= 50
4) here to find midpoint use the formula
x1 + x2/2 , y1 +y2/2
here (5,2) and (7,6)
( x1,y1) (x2,y2)
so 5+7/2 = 6 and 2+6/2 = 4
so answer will be (6,4)
5) answer will be three
because it touches the x axis at three points
6) 1.5
7) here if D > 0 so the roots has real and distinct roots
8) l. c. m (a, b) = ab/ g. c. d(a,b)
l. c. m= 8*20/4 = 160/4 = 40
