Which expression does not belong? <br><br><br><br> (2c−d)(2c−d) (2c+d)(2c−d) (2c+d)(2c+d) (c+d)(c+d)
zlopas [31]

Answer:

It could be any of them.

Step-by-step explanation:

First off, It could be said that (2c-d)(2c-d) doesn't belong because it includes two subtractions signs and none of the others do.

Secondly, It could be said that (2c+d)(2c-d) doesn't belong because it includes one subtraction sign and one addition sign and none of the others do.

Thirdly, It could be said that (2c+d)(2c+d) doesn't belong because it includes two addition signs, and none of the others do.

Finally, it could be said that (c+d)(c+d) doesn't belong because it doesn't have a multiplying factor of 2 within the parentheses.

I hope this helps :)

Given the equations 4x−py=6 and 5x+7y=10, find (a) the value of p that makes the lines parallel and (b) the value of p that make
Lubov Fominskaja [6]

Step-by-step explanation:

(a) the value of p that makes the lines parallel :

=> -4/-p = -5/7

5p = 7×(-4)

5p = -28

p = -28/5 = -5.6

(b) the value of p that makes the lines perpendicular :

=> -4/-p = -1 ÷ (-5/7)

4/p = 7/5

7p = 4×5

7p = 20

p = 20/7 = 2.86
