If 64x3 - 343y3 = (4x - Ay) X (Bx2 + 49y2 + Cxy), then find the value of 3 X (2A + 6B) - 2C.
If a + b + c = 8, aΒ² + bΒ² + cΒ² = 18 and ab + b c+ ca = 12, then what is the value of aΒ³ + bΒ³ +cΒ³ β3abc?
If Β
Β = 4 then Β
(a + 7)2 + (b β 2) 2 + (c + 3) 2 = 0, then find the value of 3a - 2b + c.
Two positive numbers differ by 2, and the sum of their reciprocals is 3/4. What is the larger number?
(x + 1)2 + (y β 3) 2 + (z + 5) 2 = 0, then find the value of 2x + 3y - z.
If x + 1/x = 5, then x2 + 1/x2 is:
(x β 6) 2 + (y + 2) 2 + (z β 4) 2 = 0, then find the value of 4x - 3y + z.
22% of βxβ is equal to 66% of βyβ, then find the value of x: y.
