What is the area of rectangle ABCD in square units

I don't see a picture of the rectangle but all you would have to do s multiply the width of the rectangle by its height.

AxB = CxD

Therefore AxB = AB^2

CxD= CD^2

AB^2 = CD^2

Step-by-step explanation:

i think it is x = 1.2

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
