when x =4 and y =-6 then find the value of 27x³ +58x²y +31xy² +8y³?

If x : y : z = 4 : 5 : 9, and (3x + 2z) = 120, then find the value of 3y.

If p = 27 - q - r and pq + r(q + p) = 168, then find the value of (p² + q² + r²).

If x = 15

find x ⁵ - 16 x ⁴ + 16 x ³ - 16 x ² + 16 x  - 16 = ?

Find the value of ‘x’ in the given expression:

(49/16)^x × (64/343)^x-1 = 4/7

If 343x³ - 27y³ = (7x - Ay) X (Bx² + y² + Cxy), then find the value of 3 X (2A + 6B) - 2C.

If (6x + y) = 180 and 5x:2y = 25:12, then find the value of (2x² + 5y²).

If 512x³ - y³ = (8x - Ay) X (Bx² + y² + Cxy), then find the value of 3 X (2A + 6B) - 2C.

If a + b + c = 9 and ab + bc + ca = 20, then find the value of a² + b² + c².
