The area of a kite is the (product of diagonal lengths)/2.A = (12 * 6)/2A = 36cm^2

We have 8x + 9y = 3 [1] and x + y = 0 [2].We can make x or y the subject. Take y as subject we have y = -x [3].We substitute [3] into [1] and get 8x - 9x = 3 --> -x = 3 --> x = -3.Substituting x = -...

Y=(x+5)(x+3) ............(1)The above expression on the right is a product of two expressions,Hence, product rule differentiation method will be employed as stated below:Y(u,v)=U(x).V(x) .........(2)dy/dx...

Pythagoras' theorem states that in any right-angled triangle the square of the longest side (called the HYPOTENUSE) is equal to the sum of the squares of the other two shorter sides.If th...

First take the 3 over the other side to make the right hand side zero, turning it into a homogeneous equation: 3a²+4a-2=0. Since the expression on the left hand side cannot be factorised, we ha...
