Answer:
3w + 8 – w = 4w – 2(w – 4)
Step-by-step explanation:
The simplified forms of each of these equations are ...
- 2w +8 = 2w +8 . . . . . .the identity you're looking for
- 7m -5 = 7m +7 . . . . . . never true
- -3y +3 = -3y -6 . . . . . . never true
- -2v +6 = -2v -6 . . . . . . never true
Compresses or stretches it
Perimeter = 300
Area = a(w)
Width = w
Perimeter = 300 and width = w ⇒ length = [300 - 2w ]/2 = 150 - w
Area, A = width * length = w(150-w) = 150w -w^2
Roots = w = 0 and w =150
Vertex
w =[0 + 150]/2 = 75
A = 75(150-75) = 75^2 = 5625
(75,5625)
Given that the coefficient of w^2 is negative, the vertex is the maximum of the function or area.
The second coordinate of the vertex (5625) is the maximum area the fence can enclose.
Answer: the maximum area that can be enclosed by the fencing.

Answer : If it is perpendicular to the axis, then a circle. If it is at an angle to the axis, then an ellipse. If it is parallel to the axis, then two parallel lines. Those are the only 3 cases that I can think of.
