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)

Answer:
4/5
Step-by-step explanation:
I'm not exactly sure what this question is asking but I'm guessing it's asking to create a fraction with the numerator as 4 and denominator as 5.
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.
Solving, we get 40 = 2x, x =20
The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.
Hope this helped!
