Answer:

length = 9 units

Step-by-step explanation:

l = length

n - 6 = width

A = n(n - 6)

A = n² - 6n

27 = n² - 6n

n² - 6n - 27 = 0

(n + 3)(n - 9) = 0

n = -3, n = 9

length must be 9 because it cannot be a negative value

F(1)=−2<br> f(2)=5<br> f(n)=f(n−2)⋅f(n−1)<br> f(3) = ?

3241004551 [841]

<h3>Answer: -10</h3>

Work Shown:

f(n) = f(n-2)*f(n-1)

f(3) = f(3-2)*f(3-1)

f(3) = f(1)*f(2)

f(3) = -2*5

f(3) = -10

Solve the equality, - (7c-18)-2c>0

Gwar [14]

(7c-18)-2c>0

group like terms: 7c-2c-18>0

add similar elements: 7c-2c=5c
5c-18+18>0+18

Add 18 to both sides
5c-18+18>0+18

simplify
5c>18

divide both sides by 5
5c÷5>18/5

simplify
c>18/5
