Answer:
l = 10 m
w = 5 m
Steps:
Set equations:
l = 2w
30 = 2l + 2w
Substitute 2w with l in second equation to find l:
30 = 2l + 2w
30 = 2l + l
10 = l
Plug in 10 into first equation to find w:
l = 2w
10 = 2w
5 = w

It should be noted that the relationship is not linear based on the information illustrated as the difference between the numbers aren't the same.
<h3>How to illustrate the information?</h3>
It should be noted that an equation is simply used to illustrate and express the relationship between the variables.
It should be noted that for the relationship to be linear, it's essential that they've the same relationship between them.
When x = 1, y = 4.5. The
When x = 2, y = 6.5
When x = 3, y = 8.5
When x = 4 y = 11.5
It should be noted that there's a difference of 2 at first but between 3 and 4, there is. a difference of 3.
Therefore, the relationship is not linear.

Answer:
7n + 1/5 + 2q
Step-by-step explanation:
Identify like terms
(4n + 3n) + (6/35 + 1/35) + (6q -4q)
Add like terms
7n + 7/35 + 2q
7/35 simplifies to 1/5
