If we denote the side of the square piece of cardboard with x, then the dimensions of the box are: height = 2 cm length = x - 4 cm width = x - 4 cm V = lwh = 392 cm^3 So we have: 2(x - 4)(x -4) = 392 divide by 2 to both sides; (x - 4)(x - 4) = 196 (x - 4)^2 = 196 x - 4 = square root of 196 (because the dimensions are to be positive) x - 4 = 14 x = 18 Thus the original size of the cardboard is 18 x 18 cm.

(-9x^2/√x) + 4= [-9x^2/x^(1/2)] + 4= (-9x^2)[x^(-1/2)] + 4= -9x^[2 + (-1/2)] + 4= -9x^(2 - 1/2) + 4= -9x^(3/2) + 4= -9√x^3 + 4= -9√[(x^2)(x)] + 4= -9x√x + 4Or,(-9x^2/√x) + 4= [(-9x^2)(√x)/(√x)(√x)] + 4= [(-9x^2)(√x)/√x^2] + 4= [-9(x)(x)(√x)/x] + 4 simplify x= -9x√x + 4
