Multiply. −5m(−2m6+4m4+m−9) express the answer in standard form. enter your answer in the box.

First distribute the -5m to get 10m^2*-30m-20m^2*-20m-5m^2+45m. After that simplify to get -15m^2-10m

Im trying to answer the question myself on the 2.14 unit test and i got:

10m^6-20m^4-5m^-9

im sorry if its not right, just know if its wrong i sacrificed 3 points off my unit test. lol

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
