Answer:
=
Step-by-step explanation:
(length of sqaure) x (width of square) =
since the length and width are the same for a square we can use the same letter for both length and width. If we chose 'a' to represent length and width then the formula can be rewritten:
(length of sqaure) x (width of square) =
l x w =
l = w = a
a x a =

Answer:
A(t) = 200+15t(1+0.02)^{t}
Step-by-step explanation:
Since the interest is calculated on the new balance every year.
Hence the formula used for compound interest is:
A = P(1+^{nt}
where, A =Amount after t years
P =Principal amount
200 is the initial balance and Since, here the $15 is added to the balance each year. Therefore, P = 200+15t
r = rate each year (0.02)
t = time (in years) (t)
n = no. of times the interest is compounded in a year (n=1)
Therefore, the recursive formula is:
A(t) = 200+15t(1+0.02)^{t}
put x = (-1)
put x = (z)
put x = (x+1)
put x = (√2 + 1 )
