A rectangular sandbox has a length that is 2 feet longer than its width. Let w represent the width of the sandbox in feet. The entire sandbox is surrounded
by a 3-foot-wide cement walkway.
What does the algebraic expression w(w+ 2) represent in this context?
the total area of the sandbox and walkway
the perimeter of the sandbox only
the area of the sandbox only
the perimeter of the walkway only

12 point are triangles pqr and stu congruent? what is the congruency that proves they are congruent? what is the perimeter of triangle pqr?

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined
