Answer:
Neither
Step-by-step explanation:
5 x -10 = -50
4 x 9 = 36
-50 + 36 = -14 and therefore can not be orthogonal
sqrt(25+16)=sqrt(41)
sqrt(100+81)=sqrt(181)
sqrt(41) x sqrt(181) is not equal to -14 so therefore it is not parallel
So the answer is then neither
30^2= 30×30=900 so 30^2 is the answer
The correct answer is y= |x + 1| - 3
600×3.5%=21. As a result, there are 21 phones that likely to be defective. Hope it help!
