Answer:
x = 3, y = 2.
Step-by-step explanation:
I assume that O is the point of intersection of the diagonals. The diagonals of a parallelogram bisect each other so here we have AO = OC and DO = OB.
Therefore 5y + 1 = 6y - 1
1 + 1 = 5y - 5y
2 = y.
2(x + 1) = 3x - 1
2x + 2 = 3x - 1
2 + 1 = 3x - 2x
3 = x.
Assuming

. We have Lagrangian

with partial derivatives (set to 0)[/tex]





Solving this system of linear equations yields

and

as the sole critical point, which in turn gives a maximum value of

.
I think 1/8 but I'm not really sure
The answer is going to be B since the person is looking for proof that the triangles are equal by SAS (Side-Angle-Side). Two sides are already proven congruent pairs so after this, you need <VXW and <YXZ to be congruent since it is in between the two congruent sides.
Step-by-step explanation:
length = 4.5 + w
width = w
perimeter means add all of the 4 sides
(4.5 + w) + (4.5 + w) + w + w
9 + 4w = answer
