Answer:
4, 6 and 8
Step-by-step explanation:
The perimeter is the sum of the lengths of the 3 sides, hence
2x + 3x + 4x = 18
9x = 18 ( divide both sides by 9 )
x = 2
The 3 sides have length
2x = 2 × 2 = 4
3x = 3 × 2 = 6
4x = 4 × 2 = 8
Answer:
10
Step-by-step explanation:
We're looking for 5 + 5:
x = 5 + 5
Since 5 + 5 = 10:
x = 5 + 5
x = 10
Answer: 10
Equal them to each other and you get that x=7
