Answer:
Step-by-step explanation:
Much depends on how accurate an estimate you want.
If "to the nearest hundred" would be acceptable (it's a lot of work),
Round off 542817 to 542820 and 27398 to 2740. Then you'd want to subtract 2740 from 542820. (Again, it's a lot of work.)
Otherwise round off to the nearest thousand: 543000 - 27000.
Or go to the nearest ten thousand: 540,000 - 30,000 = 510,000 (estimate)

Step-by-step explanation:
Just count how many 4.5 there are.
Step-by-step explanation:

factor it: (start by factoring out the x that is common to all 3 )

next keep factoring the inside...
![= x\left(x^2+x-4x-4\right)\\=x \left[x\left(x+1\right)-4\left(x+1\right)\right]\\=\bold{x\left(x+1\right)\left(x-4\right)}](https://tex.z-dn.net/?f=%3D%20x%5Cleft%28x%5E2%2Bx-4x-4%5Cright%29%5C%5C%3Dx%20%20%5Cleft%5Bx%5Cleft%28x%2B1%5Cright%29-4%5Cleft%28x%2B1%5Cright%29%5Cright%5D%5C%5C%3D%5Cbold%7Bx%5Cleft%28x%2B1%5Cright%29%5Cleft%28x-4%5Cright%29%7D)
