(1600,3600) you multiply the 4X400 and 9X400
The answer should be jet streams. :)
Hello,
N is closed for an opération(µ) means that
a,b ∈ N : a µ b ∈N (i suppose so)
Answer (1) ex 2/3 ∉ N
Answer (4) ex 2-3 ∉ N
∀ a,b ∈ N: a+b ∈N is true ; not a answer.
∀ a,b ∈ N: a*b ∈N is true ; not a answer.
15 cm^2
A= 5*6/2= 30/2= 15 cm^2
Answer:
The length of mid-segment
units
Step-by-step explanation:
Given:
Length of
units
is the mid-segment which means the line joining the midpoints of two sides of triangle.
By mid-segment theorem the mid-segment of a triangle is parallel to the third side and half of the length of third side.
So, we can write:
∴
units
∴The length of mid-segment
units
