AIDER MOI SVP 7 (x+2)= 3(2x+2)= 4(2x-4)= 3(2x-3)= 8+3(2x+9)= DE L AIDE SVP​

Réponse:

7(x+2) = 7*x + 7*2

= 7x +14

3(2x+2)= 3*2x + 3*2

= 6x +6

4(2x-3)= 4*2x - 4*3

= 8x - 12

3(2x-3)= 3*2x - 3*3

= 6x - 9

8+3(2x+9)= 8+3*2x+3*9

= 8+6x+27

= 6x+ 35

Réponse:

1. 7x+14

2.6x+6

3.8x-16

4.2x-3

5.22x+99

[tex]7 \times x + 7 \times 2[/tex]

2.

[tex]3 \times 2x = 6x \\ 3 \times 2 = 6 \\ = 6x + 6[/tex]

3.

[tex]4 \times 2x = 8x \\ 4 \times ( - 4) = - 16 \\ = 8x - 16[/tex]

4.

[tex]3 \times 2x = 6x \\ 3 \times ( - 3) = - 9 \\ = 6x - 9[/tex]
