Answer:
perimeter = 20 m
Step-by-step explanation:
given the area of the square = 25 m² and
area of a square = s² ( where s is the side length ), then
s² = 25 ( take the square root of both sides )
s = = 5 ← length of side
perimeter = 4s = 4 × 5 = 20 m
Answer:
Step-by-step explanation:
Given is a trignometric equation in x, as
TO make it in one trig ratio, we can replace sin2x as 2sinx cosx
WE get now
Principal solution is
x = ±π/2 + 2kπ, where k is any integer or
x=±pi/6 +k pi, where k is any integer.
General solution is
Answer:
No, middle term should be 40x.
Step-by-step explanation:
Hence, for the given trinomial to be a perfect square its middle term should be 40x and not 36x.
