The Correct Answer is A.
Step-by-step explanation:
Answer:
<h2><u><em>
2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u></h2>
Step-by-step explanation:
Write an expression for the perimeter of a rectangle with a length of
(3x² + x + 2) and a width of (-x² – 5x + 1).
P = 2 × (L + W)
<u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u>
if you want the result:
4x²−8x+6

Answer:
the average rate of change is 4.
Step-by-step explanation:
Find the average rate of change of f(x)=x^2 on the interval [1,3].
The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)/b−a.
We have that a=1, b=3, f(x)=x^2.
Thus, f(b)−f(a)/b−a=((3))^2−(((1))^2)/3−(1) = 4.
