60-38 = 22 females 32+12=44 students taking the Chemistry and Maths exam. Therefore 60-44=16 students were doing the Physics exam, so 16-8= 8 females were taking the Physics exam. This means that 22-11-8 ...

The lengths of a right angle triangle can be summarised as follows: the sum of the lengths of the two shorter sides squared (the sides which vertice connect forms the right angle) is equal to square of th...

3y² + 10y + 33y² = 3 * 1(3y + n) * (y + r)n * r = 3 hence to try whole numbers first n = 1 or 3 meaning r = 3 or 1 respectivey * n + 3y * r = 10yif n =1 and r = 3 then equivalent is ...

n > 1, n <4.rearrange equations.use the quadratic formula to solve the second equation. look at the boundaries set and formalise which are the answer.

The question is asking us to "solve" the equation which means we need to find the missing variable. In this case, x is our missing variable so our goal is to get all the x's on ...
