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)
<h3>Meaning of algebra</h3>

600 is the answer ur welcome
Answer:
Absolute error = 39
Percent Error = 6.10%
Step-by-step explanation:
Actual value = 639 pounds
Observed Value = 600 pounds
The formula to find absolute error is:
Absolute Error = Actual value - Observed Value
= 639 - 600
= 39
The formula to find Percent error is:
Percent Error = (Actual value - Observed Value / Actual value)*100
= (639 - 600/639)*100
= 6.10%
