K = -8 is the correct answer
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)

Is a problem solving method that uses that fact that any number or expression can be multiplied by one without changing it's value.
The answer is (4/5). If you multiply the first (5/12) over and over, you get this sequence.
If you would like to know how many free throws did a basketball player attempted, you can calculate this using the following steps:
75% of x is 84
75% * x = 84
75/100 * x = 84
x = 84 * 100 / 75
x = 112 free throws
The correct result would be 1<span>12 free throws.</span>
