If the expression (x^2+2x−1)^8 is completely expanded, what is the sum of the coefficients of the terms with even powers of x?
A cube of edge 12 cm is cut into 64 equal cubes. All the cubes are now arranged on a table such that one face of each cube touches the table. The resulting figure is a solid cuboid whose length and breadth are in the ratio 4 : 1 respectively. What is the total surface area of the table occupied by the cuboid?(a) 144 cm2 (b) 288 cm2 (c) 576 cm2 (d) None of these👍

576.. Same approach as @vK3105

sir
the equations eventually become all-out-of-the-world complex for me.😠
where am i going wrong with this approach.??
please help. :(
1. -3.5
2. -5
3. -8
4. None of these Skip

None of these, I am getting a minimum value of -5.5
f(x) is a polynomial with integer coefficients and degree at most 10. There are N distinct integer value for which f(n)=2 , and M integer values for which f(m) = -2 . What is the maximum possible value of NM .?
There is an isosceles right angle triangle PQR right angled at R.X is a point inside the triangle.If PX=5, QX=13 and RX=6√2, find the area of the triangle PQR.
(A)137/2
(B)56
(c)193/3
(D)77
(E)None of these
None of these, I am getting a minimum value of -5.5
can u share the approach, my approach is as follows... the critical points are -2.5, 3, 8.. so as there is a negative sign the range btwn -2.5 to 8 is -10.5 and range between 3 and 8 is 5...so (overall -10.5 +5 = -5.5... I am nnot sure if the approach is correct..rectify if needed
There are 100 players numbered 1 to 100 and 100 baskets numbered 1 to 100.The 1st player puts 1 ball each in every basket starting from first basket(i,e the baskets numbered 1,2,3...)the second player puts 2 balls each in every second basket starting from the 2nd basket ( i,e basket numbered 2,4,6....) and so on till the 100th player.
A) Which basket will have maximum no of balls 1) 96 2) 98 3) 100 4) 90
B)How many baskets will exactly have twice the no of balls as the no on the basket itself?👍

1. A and B are the two opposite ends of a swimming pool and the distance between them is420 metres. Ankur and Manu start swimming towards each other at the same time from A and B,with speeds in the ratio 5 : 9 respectively. As soon as any of them reaches an end, he turns backand starts swimming towards the other end. At what distance (in metres) from A will they meet whenManu is in his 13th round? Note: A to B is considered one round and B to A another round.(a) 405 (b) 330 (c) 240 (d) 280
