What you have written here is an equation.
You can define as
a2+b2=y
If you want to derive a^2+b^2 from ( a+b)^2
(a+b)2=a2+b2+2ab
Ora2+b2=(a+b)2−2ab
Answer:
360 feet
Step-by-step explanation:
multiple 6 by 12 to get the area of the individual plot of land given to a single worker.
Then multiply by 5 for all 5 workers getting the same plot of land.
Answer:
I am very proud he is showing his work
Step-by-step explanation:
This is an Arithmetic Progression with 1st term 11 and common difference d=6
Number of Rows Number of seats Common difference " d"
----------------------- ----------------------- -------------------------------------
1st a₁ = 11
2nd a₁+d =17 d =2nd - 1st = 6
3rd a₁ +2d = 23 d =3rd - 2nd = 6
4th a₁ +3d = 29 d= 4th - 3rd = 6
-------------------------------------------------------------------------------
nth ROW a(n) = a₁ + (n-1)d
18th ROW a₁₈ = 11 + (18-1).6 = 11+(17)(6) = 113
General equation to predict the number of seat an the nth row:
Number of seats in nth row = a₁ + (n-1).d
$65 if you include the $20 he already had in his account
