Answer:
A
Step-by-step explanation:
The coordinates are (3,5),(7,-3),(0,-5),(-3,-4) and (-6,1). So the correct option is A
Answer:
1). 250 - 60t
2). 60t
Step-by-step explanation:
"Camila started her collection with 250 cards and decreased by 60 cards each year"
Starting number of cards with Camila = 250
Decrease in number of cards each year = 60
Decrease in number of cards after 't' years = 60t
Number of cards after 't' years = 250 - 60t
"Camila didn't have any card when she started her collection, but her collection grew by 60 cards each year."
Number of cards with Camila = 0
Number of cards grew each year = 60
Number of cards after 't' years = 60t + 0 = 60t

Parallelogram
The most precise term for quadrilateral ABCD with vertices A(4, 4), B(5, 8), C(8, 8) is a kite.
Option C is the correct answer.
A kite is a quadrilateral where the adjacentsides are equal which means there are two pairs of equal sides.
We have,
Quadrilateral ABCD:
A = (4, 4)
B = (5, 8)
C = (8, 8)
D = (8, 5)
Now,
A__________B
| |
| |
| |
D_________ C
We see the distance between the two points.
AB = √(8 - 4)² + (5 - 4)² = √(4² + 1) = √17
AD = √(5 - 4)² + (8 - 4)² = √(1² + 4²) = √17
AB = AD
BC = √(8 - 8)² + (8 - 5)² = √9 = 3
CD = √(5 - 8)² + (8 - 8)² = √9 = 3
BC = CD
AB and AC are adjacent sides.
CD and DB are adjacent sides.
So,
The quadrilateral ABCD is a kite.
Thus,
The quadrilateral ABCD is a kite.

Answer:
Eduardo necesita 64 metros de malla para cercar el terreno completo.
Step-by-step explanation:
Por Geometría recordamos que un cuadrado es una figura geométrica con cuatro lados de igual longitud y cuatro ángulos internos rectos. Hallamos la longitud del lado frontal por la Ecuación General de la Longitud de un Segmento de Recta:
(Eq. 1)
Donde:
, - Componentes independientes inicial y final, medidos en metros.
, - Componentes dependientes inicial y final, medidos en metros.
- Longitud del segmento de recta, medidos en metros.
Si conocemos que y , entonces la longitud del segmento de recta es:
El metraje requerido para cercar el terreno es el perímetro de ese lugar, es decir, cuatro veces la longitud del lado frontal. Es decir:
(Eq. 2)
Donde es el perímetro del cuadrado, medido en metros.
Si , entonces el metraje requerdo para cercar el terreno es:
Eduardo necesita 64 metros de malla para cercar el terreno completo.
