Answer:
answer is 3
Step-by-step explanation:
they are correct
3
It's given that ΔDEF ∼ΔXYZ . So the corresponding sides of both triangles will be proportional to each other.
DE = 4 ; XY = 4(n + 1) ; EF = 5 ; YZ = 7n - 1
Putting all these values gives ,
B
If you multiply both 2.3 x 1.98, you get 4.55
