These types of questions can sometimes throw people off due to the quadratic nature of the second equation but don't fret; we'll use a method called substitution to find the answer! Firstly, we rearrange the...

We are searching for a rule that when we put in n (n represetning where the term is in the sequence eg. 3 is the first term so n will be 1) our output is the sequence above. This rule will most likely be in ...

5x - 2 < 3x + 11 --> 5x < 3x + 13 (Add 2) --> 2x < 13 (Subtract 3x) --> x < 13/2 (Divide by 2)

First, we start by moving the x's all over to one side. These are our undefined variable and it is important to keep them together. To do this, we take away 3x from either side and we get: 3x - 3 > 9 Now,...

The interior angle of a regular shape is the angle found on the inside of the shape at each of its corners. A twelve-sided regular polygon is too complex to remember its geometric rules so we must divide it ...
