Answer:

The length of each wall is 22 ft.

Step-by-step explanation:

Consider the provided information.

It is given that the length of each section of plants is equal.

Let the length of each plant is x.

Thus, the length of each side is 7-ft storage area and 5 sections for different kinds of plants. i.e.

Length of one side = 7 + 5x

Similarly, on the opposite wall is a 4-ft storage area and 6 sections for plants. i.e.

Length of opposite side = 4 + 6x

For better understanding refer the figure 1:

As we know in a rectangle opposite sides are equal, thus.

7 + 5x = 4 + 6x

Solve for x.

7 - 4  =  6x-5x

x = 3

Thus, the length of one side is:

7 + 5(3) = 7 + 15 = 22 ft

Hence, the length of each wall is 22 ft.

Note: it is not possible to find the length of other two wall as there is no information related with them.

Find all pairs of natural numbers which can be the solution to the equation a+b=42.
Setler [38]

Answer:

(1,41), (2,40), (3,39), (4,38), (5,37), (6,36), (7,35), (8,34), (9,33), (10,32), (11,31), (12,30), (13,29), (14,28), (15,27), (16,26), (17,25), (18,24), (19,23), (20,22), (21,21), (22,20), (23,19), (24,18), (25,17), (26,16), (27,15), (28,14), (29,13), (30,12), (31,11), (32,10), (33,9), (34,8), (35,7), (36,6), (37,5), (38,4), (39,3), (40,2), (41,1).

Step-by-step explanation:

To find all pairs of natural numbers which are solution to a+b=42, we need to first choose a value to one of them (let's choose 'a'), and that value will be the lowest possible, so we begin with a=1, and then we increase to 2, and 3, and so on.

For each value of a, we calculate the value of b using the equation.

So, starting with a=1, we have that b=41

Then, with a=2, we have that b=40, and so on.

Doing this until a=41 (so b=1 will be the lowest value possible for b), we have the pairs of natural number we want:

(1,41), (2,40), (3,39), (4,38), (5,37), (6,36), (7,35), (8,34), (9,33), (10,32), (11,31), (12,30), (13,29), (14,28), (15,27), (16,26), (17,25), (18,24), (19,23), (20,22), (21,21), (22,20), (23,19), (24,18), (25,17), (26,16), (27,15), (28,14), (29,13), (30,12), (31,11), (32,10), (33,9), (34,8), (35,7), (36,6), (37,5), (38,4), (39,3), (40,2), (41,1).
