You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
Answer:
False
Step-by-step explanation:
x
The opposite of x is -x
x* -x = -x^2
This is not always 1
If it is a rhombus then you know each side is the same length, so only have to work out one side. To do this you have to use Pythagoras' theorem (a^2 + b^2 = c^2)
So take two sets of coordinates, for example, (0,3) and (5,3), a and b represent the height difference and the length difference. Therefore (5-0)^2 + (3-3)^2 = c^2
c^2 = 25
c = 5 , which would be the side of the rhombus
Answer:
D) Consistent and Independent
Step-by-step explanation:
The system of equations,
and

is consistent and independent if 
The system is consistent and dependent if 
The system is inconsistent if 
Now, in the given system
4x - y + 3 = 0 and
2x - y - 4 = 0


So, 
Hence, the given system is consistent and independent.
