Given 21% of 500 + 31% of 1100 - 30% of 790 = ?

? = 21 x 5 + 31 x 11 - 3 x 79

? = 105 + 341 - 237

? = 446 - 237

? = 209.

The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls.

(3x + 2) (2x - 5) = ax2+kx+n ...............(1)

But (3x + 2)(2x - 5) = 6x2-11x-10........(2)

so by comparing (1) & (2),

we get a= 6, k= -11 , n= -10

(a - n + k) = 6 + 10 - 11 = 5.
