Having trouble please help me !!

213

Step-by-step explanation:

Use the triangle area formula : ×bh

b = length       h = height

b = 14.8 + 5.2      h = 21.3

1)   × (14.8 + 5.2) (21.3)

Add the numbers in the parenthesis.

2)   × (20) (21.3)

Multiply the parenthesis.

3) × 426

Reduce the numbers with the greatest common factor: 2

4) 213

  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).
