The rectangle to the right has a width of 2x^7 feet and length 4x^9 feet. find it’s area as an expression of x.

8x^16

Step-by-step explanation:

(2x^7)(4x^9)

2x•4x=8x

Since the bases are the you add the exponents so 9+7 =16

8x^16

  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).
