When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:

After this, we merely need to simplify the answer.


Simplifying 12/2 gives us the answer 6.
26 minus 3 is 23 , 23 minus 5 is 18, 18 minus 7 is 11 so i’m pretty sure
answer =11
To solve this problem you must apply the proccedure shown below:
1- You have the following information given in the problem above:
- <span>The square of the diagonal of the rectangle is equal to the sum of the squares of the length and the width.
- The length is 25 meters and the diagonal is 45 meters.
2- Therefore, you have:
x: diagonal of the rectangle.
x^2=l^2+w^2
3- You have:
w^2+l^2-x^2=0
w^2+(25)^2-(45)^2=0
w^2-1400=0
w=37.41
The answer is: </span>w^2-1400=0
Answer:
C is the answer according to me
