Firstly setup an equation to find the perimeter:
3x + 4x + 5x = 54, this is because perimeter is equal to sum of all side lengths
Then combine like terms:
12x = 54
Now use the division property of equality by dividing both sides by 12:
x = 4.5
So then, you will substitute the value of x for each value of the side lengths:
3(4.5) = 13.5 for AB, 4(4.5) = 18 for BC, and 5(4.5) = 22.5 for AC.
Hope this helps and let me know if you have any more questions!
Answer:
It is D
Step-by-step explanation:
You have to divide each side by k to get x by itself. So,

Answer: 98 roses
Step-by-step explanation: 2:7 is like x:343
343 divided by 7 is 49, so that is what you multiply 2 by to get the roses. 49 x 2 = 98
Step-by-step explanation:
h = 4(x+3y)+2
h = 4x + 12y + 2
4x = 14y
1. given
2. corresponding parts theorem
- segments AB and DB are similar
and segments BC and BE are also similar. lastly the circle at angles C and E indicate that they are congruent
3. SSA similarly theorem
AB and BC are similar and BC and BE are similar and angle C and E are congruent. also the triangles are not congruent in length so that makes them similar.
i apologize if i am incorrect i like just learned this. have a great day and good luck on your studies
