P=s1+s2+s3
Move +s1 to the other side. Sign changes from +s1 to -s1
P-s1=s1-s1+s2+s3
p-s1=s2+s3
Move s2 to the other side. Sign changes from s2 to -s2
p-s1-s2=s2-s2+s3
p-s1-s2=s3
Answer: p-s1-s2=s3
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:

Where:
- L represents the new length
- W represents the new width
Now, we know that each dimension is reduced by x inches, it means:


Then, we will have:

Finally, we just need to solve it for x.




<u>Therefore, the value of </u><u>x = 3.</u>
