D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle = 
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB = 
Length of BC = 
Length of CA = 
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;

Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.
Answer:
Step-by-step explanation:
nobody answered yet, its between G and H, im leaning more towards G, but J and F are definitely not the answers.
I hope this helps a little bit

10minutes= 10/60 hours
= 1/6 hrs
speed = distance/ time
=3/ (1/6)
= 18 km/h
