Pythagoras' Theorem can only be used on right angle triangles. To find the length of side a, the theorem can be used as follows:
a²=h²-b²
Taking the square root ...

The differential of f(x) is f'(x)=6x+2 because we apply this basic formula: the differential of kxⁿ = knx^n-1 where k is a constant.This ...

Firstly, look at the number in front of the x term. This is 5Then look at the number at the end without an x term. This is 6.What 2 numbers would add to make 5, and multiply to make 6?? + ? = 5 ? x ?=6Thi...

Derive an inequality for the area. 1) As area = width * length then area is 4x * (x+3). 2) Area is less than ( < ) 112 so inequality is 4x* (x+3) < 112. 3) Expan...

15 = 5^x, we can easily solve this equation by using logs on either side which will give us: log15 = x log 5. Then by solving this for x, we get the result of 1.68 to two decimal places.
