The answer for this is -12V7i
To understand the algebra, go through the following equations below:
- First the thing to note is that the top square is the square of the bottom square: Stage 1: 1 &
, stage 2 = 2 &
, stage 3 = 3 & 
- Second image: Just add the two values above to get the total of tiles needed. For stage 5: 5 +
= 30, Stage 12: 12 +
= 156
Part B
- First equation : y =
+ n
- second equation: y = n + (n*n)

The equation which represents the change in elevation of the mountain climber as he descends the cliff is; c = -2.5s.
<h3>What is the change in elevation c of the climber in terms of seconds?</h3>
It follows from the task content that the change in elevation of the climber is to.be represented by c and since the rate of descending the cliff is given as; 2.5 ft/second.
Therefore, the required equation is; c = -2.5s.
