Answer:
5 meters
Step-by-step explanation:
If the smallest rectangle has a length of 8 meters, and a perimeter of 24 meters then its width is given by:
We can conclude that the width is half of the length for both rectangles. Therefore, the width of the larger rectangle, with a perimeter of 30 meters, is:
The width of the original rectangle is 5 meters.
Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.

Answer:
Step-by-step explanation:
Given the function f(x)=x-3
So we want to know the value of the function when
1. x=1
Then, f(x) =x-3
Let substitute x=1
f(1)=1-3
f(1)=-2
2. x=2
Then, f(x) =x-3
Let substitute x=2
f(2)=2-3
f(2)=-1
3. x=4
Then, f(x) =x-3
Let substitute x=4
f(4)=4-3
f(4)=1
4. x=5
Then, f(x) =x-3
Let substitute x=5
f(5)=5-3
f(5)=2
5. x=8
Then, f(x) =x-3
Let substitute x=8
f(8)=8-3
f(8)=5
f(x)=x-3
x. 1 2 4 5 8
f(x). -2 -1 1 2 5
