4 is an inverse because it has a pattern but 6 is not an inverse because ther is not pattern
Answer:
The constant of proportionality is 2.
Step-by-step explanation:
z^2 = kW where k is a constant.
When z = 4 , W = 8 so
4^2 = 8k
k = 4^2/8
= 16/8
= 2.
Answer: 1/2x6=3 not 1/2x5 which equals 2 1/2.
Answer:
Step-by-step explanation:
Given
Required
Select 3 equivalent expressions
Express 9 as 3^2
--- This is one equivalent expression
Take 
as difference of two squares
-- This is another equivalent expression:
Solving further:
becomes
-- This is another equivalent expression:
Hence, the equivalent expressions are:
Sum of interior angles formula = (n-2) x 180
where n = number of sides
so,
( 19-2 ) x 180
= 17 x 180
= 3060
ans : A
hope it helps :)
