Answer:
by expressing it you see that all lies negatively-32=-9=(-3)
I think it’s the third one hope this helps
The given equation is 
By solving the given equation, we get


While solving the equation,we get 0=0.
Therefore, the given equation is true for all the values of y.
Hence, we can say that the given equation has infinite number of solutions.
Answer: if this is a triangle, then all triangles add up to 180 degrees. I dont know if this helps... sorry
Step-by-step explanation:
The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse
so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.
b ) sin 45 = 1 / sqrt2 = sqrt2 / 2
c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2
