Mathematics
1 answer:
Lubov Fominskaja [6]3 years ago
6 0

Answer:

  see attachment

Step-by-step explanation:

I find the arithmetic tedious, so I like to let a calculator or spreadsheet do it. The components of the sum are the sums of the components.

___

For example, ...

  u - 5w = <11, 12> - 5×<4, -5>

  = <11 -5·4, 12 -5·(-5)>

  = <-9, 37>

  = -9i +37j

QUESTION 7<br> Solve for x.<br> (3x + 32)<br> (5x-8)<br> O a. 3<br> b. 12<br> O c. 20<br> O d. 19.5
Alchen [17]

Answer:

The answer is x = 20

Step-by-step explanation:

If you set both equations equal to each other and solve for x, you will get 20.

3x+32 = 5x-8        add 8 to both sides

3x+40 = 5x           subtract 3x from both sides

40 = 2x                 divide by 2 on both sides

20 = x

Polynomial division (-12m^2-49mn-44n^2)/(-3m-4n)
Ket [755]
First factor -12m^n - 49mn - 44n^2 to get -(4n+3m)(11n + 4m) then the equation would be:
-(3m + 4n)(4m + 11n) / (-3m - 4n)
Then, cancel out the like terms and the final answer would be
4m + 11n
