Answer:
Difference in their measurement will be 245532 mm
Step-by-step explanation:
We have given that Priya measured the perimeter of the desk and found the perimeter as 248 m
We know that ![1m =1000mm](https://tex.z-dn.net/?f=1m%20%3D1000mm)
So 248 m = 248000 m
And Noah measured the perimeter of the same desk and found as 2468 m
We have to find the difference in their measurement
Difference will be = 248000 - 2468 = 245532 mm

Answer:
![k^2-30k-18-4k^2=(k+3)(-3k-21)+45](https://tex.z-dn.net/?f=k%5E2-30k-18-4k%5E2%3D%28k%2B3%29%28-3k-21%29%2B45)
Step-by-step explanation:
Given:
![(k^2-30k-18-4k^2):(3+k)](https://tex.z-dn.net/?f=%28k%5E2-30k-18-4k%5E2%29%3A%283%2Bk%29)
Consider the expression
. First, add the like term
and ![-4k^2:](https://tex.z-dn.net/?f=-4k%5E2%3A)
![k^2-4k^2=-3k^2](https://tex.z-dn.net/?f=k%5E2-4k%5E2%3D-3k%5E2)
Now, this expression is
![-3k^2-30k-18](https://tex.z-dn.net/?f=-3k%5E2-30k-18)
Divide
by
Multiply
by
and subtract the result from the
to eliminate the highest term ![-3k^2:](https://tex.z-dn.net/?f=-3k%5E2%3A)
![-3k^2-30k-18-(-3k)(k+3)=-3k^2-30k-18+3k^2+9k=-21k-18](https://tex.z-dn.net/?f=-3k%5E2-30k-18-%28-3k%29%28k%2B3%29%3D-3k%5E2-30k-18%2B3k%5E2%2B9k%3D-21k-18)
Multiply
by -21 and subtract the result from ![-21k-18:](https://tex.z-dn.net/?f=-21k-18%3A)
![-21k-18-(-21)(k+3)=-21k-18+21k+63=45](https://tex.z-dn.net/?f=-21k-18-%28-21%29%28k%2B3%29%3D-21k-18%2B21k%2B63%3D45)
Hence,
![k^2-30k-18-4k^2=(k+3)(-3k-21)+45](https://tex.z-dn.net/?f=k%5E2-30k-18-4k%5E2%3D%28k%2B3%29%28-3k-21%29%2B45)
180/8 =22.5 22.5•20=450 miles
