Answer:
f(n) = -n^2 -3n +5
Step-by-step explanation:
Suppose the formula is ...
f(n) = an^2 +bn +c
Then we have ...
f(1) = 1 = a(1^2) +b(1) +c
f(2) = -5 = a(2^2) +b(2) +c
f(3) = -13 = a(3^2) +b(3) +c
__
Here's a way to solve these equations.
Subtract the first equation from the second:
-6 = 3a +b . . . . . 4th equation
Subtract the second equation from the third:
-8 = 5a +b . . . . . 5th equation
Subtract the fourth equation from the fifth:
-2 = 2a
a = -1
Then substituting into the 4th equation to find b, we have ...
-6 = 3(-1) +b
-3 = b
and ...
1 = -1 +(-3) +c . . . . . substituting "a" and "b" into the first equation
5 = c
The formula is ...
f(n) = -n^2 -3n +5

Answer:
The answer to your question is:
m = length of the smaller bed = 17 ft
l = length of the larger bed = 25 ft
Step-by-step explanation:
Data
A1 + A2 = 914
A1 - A2 = 336
A1 = l²
A2 = m²
Process
l² + m² = 914
l² - m² = 336
l² = 336 + m²
(336 + m²) + m² = 914
336 + 2m² = 914
2m² = 914 - 336
2m² = 578
m² = 578 / 2
m² = 289
m = 17 ft
l² = 336 + 289
l² = 625
l = 25 ft
