C) rhombus.
lines of symmetry can only go through symmetrical shapes. rhombuses are not symmetrical.
The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
The answer is that y is equal to zero
The answer is C) 0.04 becuase the 4 is in the hundredths place
