In the xy plane, a quadrilateral has vertices at (-1, 4), (7,4), (7,5), and (-1. 5). What is the perimeter of the quadrilateral?
iris [78.8K]

Answer:

(B) 18.

Step-by-step explanation:

We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).

First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.

We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.

\text{Perimeter of quadrilateral}=8+1+8+1

\text{Perimeter of quadrilateral}=16+2

\text{Perimeter of quadrilateral}=18

Therefore, the perimeter of the given quadrilateral is 18 units.

Simple...

you have: \frac{18-2*5}{15+3(-3)}

To solve this just go slowly..simplify everything out-->>

\frac{18-2*5}{15+3(-3)} = \frac{18-10}{15+3(-3)}

\frac{18-10}{15+3(-3)} = \frac{8}{15+3(-3)}

\frac{8}{15+3(-3)} = \frac{8}{15+-9}

\frac{8}{15+-9} = \frac{8}{6}

\frac{8}{6} = \frac{4}{3}

Answer is \frac{4}{3}.

Thus, your answer.

GEOMETRY PROOFS!
Elis [28]

Given that:

In ∆AMN and ∆TPE

MA = PE (Side )

∠AMN = ∠TPE (angle)

MN = PT (Side)

By SAS Property

∆ MAN =~ ∆ PET

∆ MAN =~ ∆ PET are congruent triangles .

<u>Answer:-</u> ∆ MAN =~ ∆ PET

<em>Additional</em><em> comment</em><em>:</em>

SAS Property:-

In two triangles , The two sides and the included angle are equal to the corresponding two sides and the included angle of the second triangle then they are congruent and this property is called Side-Angle-Side (SAS) Property.
