If the n\(^{th}\) term of a linear sequence (A.P) is (5n - 2), find the sum of the first 12 terms of the sequence.

If h(x) = x\(^2\) + px + 2 is divided by (x + 3), the remainder is 5, find p

If 5x + 7 \(\equiv\) P(x + 3) + Q(x - 1), find the value of p

If log\(_2^x\) = 2, evaluate log\(_x^{128}\). 

Evaluate: \(\frac{cos^2 300º - 4sin^2 120º}{tan^2 135º}\)
