2. The side of a square exceeds the side of another square by 5 cm. The difference of
their areas is 325 sq. cm. Find the sides of
each square.

Step-by-step explanation:

From the question we are told that

Sides difference

Area difference  

Let first square be A

Let second square be B

Generally the area of a square is mathematically given by

Area of a square

Area of a square

Therefore from the equations above

Therefore

Side of the first square

Side of the second square.

Check answer

  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).

answer: i think it is (1,-2)
