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 :)

217 pens and 131 pencils together cost rupees 913 while 131 pens and 217 pencils cost rupees 827 find the cost of one pen and on
melisa1 [442]

Answer:

$5

Step-by-step explanation:

Just use simultaneous equations to solve this problem.

Let cost of pens = x and cost of pencils  = y:

217 x + 131 y = 913

131x + 217y = 827

Solving these 2 equations you get: x = 2 and y = 3

Hence, cost of one pen and one pencil​ = 2 + 3 = 5 rupees
