D(1, 1), e(1,−2), f(−2,−2), g(−2, 1) the perimeter of the figure is a units.

9 units squared

Step-by-step explanation:

The figure is a rectangle with length 3 and height 3. See attached picture. The area is found using A = b*h = 3*3 = 9.

go on the tube you might find some information there

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
