Answer:
9d^2/(2d + 4).
Step-by-step explanation:
18d^2 / (4d + 8)
First factorise the denominator:
= 18d^2 / 4(d + 2)
The GCF of 18 and 4 is 2 so this simplifies to:
9d^2/2(d + 2)
= 9d^2/(2d+ 4).
Answer:
a). ΔABC ~ ΔBDC
b). m(BD) = 6 units
Step-by-step explanation:
If ΔABC ~ ΔBDC,
a). Ratio of the corresponding sides of both the triangles will be equal.




Since Ratio of the corresponding sides are same, therefore, both the triangles are similar.
b). 

BD = 
BD = 6
It should be 84500000 centimeters.
