Hello! Can anyone please help me with this? I keep getting a low score on this lesson and just want a good grade :(

Aparallelogram has two side lengths of 5 units. three of its sides have equations y = 0, y = 2, y = 2x. find the equation of the fourth side.

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Which of the following is a solution of z^6 = 64i? 2(cos105° + isin105°) 2(cos120° + isin120°) 2(cos135° + isin135°) 8(cos15° + isin15°)
