Périmètre du rectangle : 2*x + 2*2,5 = 2x + 5
Périmètre du triangle : 3*(x-1) = 3*x + 3*(-1) = 3x-3
Périmètre du triangle = Périmètre du rectangle
3x-3 = 2x+5
3x
-2x

+3
= 2x

x = 8
La longueur du rectangle jaune doit être de 8 cm pour que son périmètre soit égal à celui du rectangle violet
Vérification
Périmètre du rectangle : 2x + 5 = 2*8 + 5 = 16+5 = 21 cm
Périmètre du triangle : 3x-3 = 3*8-3 = 24-3 = 21 cm

pouvez vous me dire si c est correcte svp. merci "my favourite picture is number 2, i choose him because the teenager is really funny. She is wearing a very short skirt with boots. We can see her belly. She has many tattoos and piercings all over her body. She has dreadlocks. This girl is very eccentric. It's a punk girl. For me, i think in Britain, not many girls are like her. I think she is cool, she doesn't want the opinion of the people, she is wearing what they like."

Bonjour a tous, pouvez vous me dire si ce texte est sans fautes et bien construit. merci. "I'm Jason Burtton, but my nickname is J.B. Everybody calls me like that. I'm 21 years old, i'm a men and i'm single because i move often so i didn't have the time to begining a relationship. To this travel, i'm with my best friend : Mike Fini. He's 21 years old too and he's single for the same reason as me. This is the twenty second day, we are on the road ; it's harder and harder. We left Roleigh un North Carolina the first March 1876. We move west tout Bismarck un North Dakota. There approxymately 2 000 miles. I remmember the first day, we were stressed and sorrowful. The weather is mild enough, we had occasional showers and a few thunderstorms. We had to leave because the gold diggers attacked us by the sea. Today, it happened somethings important ; we meet Indians in Topeka in Kansas. The meeting went wrong because they thought we attacked them. They tied us a totem. There was fire next to us. It was more and more dangerous. We thought we were going killed by the Indians. But the chief of the tribe came to talk to us and it all came together. When we left, they offered their food and water, as well as covers of Buffalo skin.

Périmètre du triangle : 3*(x-1) = 3*x + 3*(-1) = 3x-3
Périmètre du triangle = Périmètre du rectangle
3x-3 = 2x+5
3x-2x-3+3 = 2x-2x+5+3
x = 8
