Question

4.
2(3x + 2)- 5(x – 2y) =
1 ) x+10y+4
2) X-10y - 4
3) -x+10y + 4
4) x-10y +4
5.
(a-b)-(a+b)=
1 ) - 2b
2) 2b
3) 2a
4) -2a​

Answer 1

Step-by-step explanation:

4). 2(3x + 2) - 5(x - 2y)

= 6x + 4 - 5x + 10y

= x + 10y + 4

option (1)

5). (a - b) - (a + b)

= a - b - a - b

= -2b

option (1)
