What is x2 11x-30?

The expression ( x^2 + 11x - 30 ) can be factored to find its roots. To factor, we look for two numbers that multiply to (-30) and add to (11). The factors are (15) and (-2), so the expression can be factored as ( (x + 15)(x - 2) ). Thus, the solutions to the equation ( x^2 + 11x - 30 = 0 ) are ( x = -15 ) and ( x = 2 ).


What is the diagonal of a 30-inch square box?

'A' squared plus 'B' squared equals 'C' squared. If 'A' and 'B' are the legs of the right angle comprising the sides of the box, 30 inches squared (900) plus 30 inches squared (900) equals 1800. The square root of 1800 is 42.426408711929.
