The answer is a, all rhombuses have equal sides, if they have equal sides then day have equal angles.
Answer: B = (6,-8)
Step-by-step explanation:
first the midpoint formula is 
then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

then solve it like an equation:

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

then solve it like an equation:

∴ the answer is x=6, y= -8
which is expressed as a point, B(6,-8)
P = W/t
W = Fd
P = Fd/t = F/t d
The factor of this expression would be 2(x+1)
It c) because it 56 out of 100
