The value of 1$\frac{3}{4}$ + 1$\frac{5}{7}$ ÷ 2$\frac{3}{7}$ × 2$\frac{3}{7}$ = ?

If the third proportional of 3x² and 4xy is 48, then find the positive value of y.

The distance between the centres of two circles having radii 22 cm and 18 cm, is 32 cm. The length (in cm) of the direct common tangent of the two circles is:
