The length of the three sides of a right angled triangle are (x-2) cm.x cm and (x + 2) cm respectively. Then the value of x is
1). 10
2). 8
3). 4
4). 0
2. If $-\frac{3}{2} + \left(\frac{2}{3}\right)(3x + 9) = $\frac{x}{2}$, then what is the value of x?
3. If m n= 2 , mn = 15 , (m , n > 0) then the value of($m^{2}-n^{2}$)($m^{3}-n^{3}$)
4. If 1.5x = 0.04y, then the value of \(\frac{{{y^2} - {x^2}}}{{{y^2} + 2xy + {x^2}}}\) is
8. The sum of interior angles of a regular polygon is $1440^{0}$. The number of sides of the polygon is
10. Simplify $\frac{(b^{2}x^{3}a^{2}z^{4})*(b^{2}x^{4}a^{4}z^{3} )}{(a^{3}b^{2}z^{4})}$
