Because the triangles are congruent,
all their corresponding sides are equal,
so 2x-9=x+5, x=14
first side : x+5=14+5=19
second side: 15
third side: 8
P = 19+8+15= 42 Answer is D

Answer:
<em>2,4,6,8,10</em>
Step-by-step explanation:
To find the first 5 terms we can substitute numbers for "n"
We can create a table:
x y
1 2
2 4
3 6
4 8
5 10
To get the values we just plug in numbers:
a(1)=2(n)
a(1)=2(1)
a(1)=2
a(2)=2(2)
a(2)=4
...... etc.
