well, we know its a rectangle, so hmmm opposite sides are not just parallel but equal, hmmm so the area of this rectangle we can get by Length * Width, in this case that'll be QT * TS

Answer:
A
Step-by-step explanation:
lmao this problem is bullshit because the actual answer would be [2, 2] U (7, infty) but thats literally not there, so ig the closest one would be [2, infty) which is A
if it was asking for the domain on the other hand, then it would be B lmao
but I would go with A
Answer:
It's hard to tell if they're dotted lines or not. If your inequality sign doesn't have a line under it then it is going to be a dotted line. If your sign is facing like this < then your shading will always be below the line graphed and if the line is facing > then it will always be shaded above the line graphed.
It's either the first picture or the second picture, but it's hard to tell with the lines provided
900 is the answer of 2 squared times 15 squared
