$\frac{12.4\times \sqrt2}{(5^2 + 6 )\sqrt{0.125}}$
$\frac{12.4\times \sqrt2}{31\sqrt{0.125}}$ = $\frac{0.4\times \sqrt2}{\sqrt{0.125}}$
0.4 x $\sqrt\frac{2}{0.125}$
0.4 x $\sqrt16$ = 0.4 x 4 = 1.6

- A factory assembles computers and normally produces 600 in x days.
i) Write down an expression involving x for the number produced per day(Solved)
A factory assembles computers and normally produces 600 in x days.
i) Write down an expression involving x for the number produced per day
ii) The rate of production is increased so that 600 are now produced in one day less (x -1). Write down an expression involving x for the number produced
iii) If the difference between these daily rates of production is 50, form an equation in x and show that it reduces to x2 - x - 12 = 0
iv) Hence find the number produced per day
