Answer:

No, it is not.

Step-by-step explanation:

Proving the opposite sides are parallel is the correct first step.  If the quadrilateral is not a parallelogram, it cannot be a rhombus.

After knowing the quadrilateral is a parallelogram, we must know whether the sides are congruent.  To do this, we must use the distance formula to find the length of each side.

Opposite sides being parallel proves that hte figure is a parallelogram.  The sides only appear to be equal so his conclusion is not valid. He would need to show that  2 adjacent sides of the parallelogram are equal ( using the distance formula)  to prove that it is a rhombus.

Is the relation in this set of points a function
natita [175]
It is not a function—an element from the domain is paired with more than one element from the range. Specifically, the input value of 4 corresponds to two output values: 5 and -4.

A function can only take on one output for each input. It only takes one input value to associate with more than one output value to be invalid as a function.

If a 25 in. by 32 in. window has a wooden frame 2 inches wide surrounding it, what is the total area of the window and frame?
d1i1m1o1n [39]

Answer:

1044 sq. inches

Step-by-step explanation:

The frame adds 2 inches on each side of the window, so the width becomes 29 in. and the length becomes 36 in.

Area = width × length

So the total area of the window and the frame is:

A = 29 × 36 = 1044 in²
