In order to find out, you need to square 45 and see weather it is equal to 40^2+30^2
in the end , 1600 won't be equal to 2500 so it won't form a right triangle.

Answer:
y = –10x
Step-by-step explanation:
A proportional relationship has the equation ...
y = kx
where k is the constant of proportionality.
Here, you are told that "[the] constant of proportionality [is] equal to –10," so you expect the equation to be ...
y = –10x
the first one
100x² + 20x +1
its a factor of different 2 squares
(10x - 1 )²
