Answer:
14x + 2
Step-by-step explanation:
Perimeter = sum of the measures of each side
If a triangle has side lengths of 3x+ 2, 6x, and 5x then the perimeter of that triangle is equal to 3x + 2 + 6x + 5x
Notice that the expression 3x + 2 + 6x + 5x has similar terms so to get the simplist version of the perimeter we would simply combine like terms
3x + 6x + 5x = 14x
The perimeter would = 14x + 2
18cms because if I take 6cms times 3cms it will equal 18cms.
Answer:
x=9
Step-by-step explanation:
subtract 9 from both sides.
-3x = -27
divide by -3
x=9
