Answer:
length =3 feet
width = 1feet
Step-by-step explanation:
let the length be x
the width = x-2
area = length * width
3 = x*(x-2)
3 = - 2x
(x-3)(x+1)=0
x -3=0
x=3
thus,
the length =x =3 feet
the width =x-2 =3-2 = 1feet

Answer:
A. On the first day, 3 leaves fall.
B. D. The number of leaves that fall on a given day is 2 times the number of leaves that fell on the previous day.
Step-by-step explanation:
Given
Solving (a) The meaning of 3.
3 represents the initial number of leaves (i.e. the first day) and this proved as follows.
On the first day, n = 0.
Substitute 0 for n in
Solving (b) The meaning of 2.
2 represents the rate which leaves fall down.
In (a)
Take n = 1
Substitute 1 for n in
When f(1) is divided by f(0), the result 2. So, the number of leaves doubles everyday
