Verify that the symmetric difference quotient produces the exact derivative value for a quadratic function f(x) = ax2 +bx+c. (Hint: Show that
f(x +h)-f(x-h)/2h
= 2ax + b
provided h≠0)

The perimeter of a rectangle is 42 inches. if the width of the rectangle is 6 inches, what is the length

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
