6.	one side of a parallelogram is 5cm more than other . if the perimeter of a parallelogram is 22cm, find the sides of parallelogram
Answer» Hello...☺ Here is your solution......☺ _____________________________ ✴ LET the ONE side of a parallelogram be "X" cm ✳ Another side = (x + 5)cm ⭐ Perimeter = 22 cm ( given ) => 2[ x + (x + 5)] = 22 Since, opposite side of a parallelogram are equal . Therefore perimeter of parallelogram is equal to 2( l + b ) => 2( 2x + 5) = 22 => 4X + 10 = 22 => 4x = 22 - 10 => 4x = 12 => x = 12/4 => x = 3 ✴ Therefore, one side of a parallelogram = x = 3cm Other side = ( x + 5 )cm = 3 + 5 = 8 cm Thanks...☺

Answer» 1. (a+B+c)^3 = a^3+b^3+c^3 + 3(a+b)(b+c)(a+c) 2. a^3+b^3+c^3 - 3 a b c = (a+b+c)(a^2+b^2+c^2 - a b - b c - a c) Also note that (a^2+b^2+c^2-ab-bc-ac)=1/2((a-b)^2+(b-c)^2+(a-c)^2) From equation 2. above, note that If a + b + c = 0, then a^3+b^3+c^3 - 3 a b c = 0 So a^3+b^3+c^3 = 3 a b c

15.	places A and B are 30 km apart and they are on a straight road. Hamid travels from A to B on bike. At the same time Joseph starts from B on bike, travel towards A . They meet each other after 20 minutes. If Joseph would have started from B at the same time but in the opposite direction (instead of towards A) Hamid would have caught him after 3 hours. Find the speed of Hamid and Joseph.
Answer» Let the speed of Hamid be ' x ' km/HR and The speed of Joseph be ' y ' km/hr Total Distance from A to B = 30km according to the problem given , i ) when Hamid and Joseph travel in opposite DIRECTION , then relative speed = ( x + y ) km/hrthey meet in 20 minutes = 20/60 hr = 1/3hrRelative speed = distance/ time x + y = 30/ ( 1/3 )x + y = 90 ---- ( 1 ) ii ) when they travel in same direction , relative speed = ( x - y ) km/hrthey meet in 3 hr relative speed = distance/time x - y = 30/3 x - y = 10 ----( 2 )ADD equations ( 1 ) and ( 2 ) we get,2x = 100 x = 100/2x = 50put x = 50 in equation ( 1 ), we get y = 40 Therefore ,speed of the Hamid = x = 50 km/hrspeed of the Joseph = y = 40 km/hr I hope this HELPS you.
