The length of the rectangle or classroom floor is 19 feet less than twice the width. which expression represents the area of the classroom floor?
a) 6w-38
b) 2w (squared) -19w
d) 3w-19

B

Step-by-step explanation:

The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
