El área a cubrir es de 4800 cm^2.
Step-by-step explanation:
<em>La pregunta está incompleta:</em>
<em>Laura quiere cubrir con papel de china una puerta como la que se muestra en el dibujo cuánto es centímetros cuadrados. Las medidas son 80 cm de largo y 60 cm de ancho.</em>
Tenemos que calcular el área que representa la puerta, cuyos lados son 80 cm y 60 cm.
El área A se calcula multiplicando ambos lados:
Answer:
n=-16
Step-by-step explanation:
Add 4 on each side:
n/2 = -12+4
n/2 = -8
Multiply 2 on each side:
n=-16
Since 1/2 is 1 whole that means it’s (1x1x1x1) and (1x1x1x1x1x1x1) meaning that they both equal to 1 meaning your question is! Yes
Answer:
2/3
Step-by-step explanation:
List all the possible sums. If it helps, make a table:
![\left[\begin{array}{ccccccc} &1&2&3&4&5&6\\1&2&3&4&5&6&7\\2&3&4&5&6&7&8\\3&4&5&6&7&8&9\\4&5&6&7&8&9&10\\5&6&7&8&9&10&11\\6&7&8&9&10&11&12\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccccccc%7D%20%261%262%263%264%265%266%5C%5C1%262%263%264%265%266%267%5C%5C2%263%264%265%266%267%268%5C%5C3%264%265%266%267%268%269%5C%5C4%265%266%267%268%269%2610%5C%5C5%266%267%268%269%2610%2611%5C%5C6%267%268%269%2610%2611%2612%5Cend%7Barray%7D%5Cright%5D)
There are 36 total possible sums. Of those, 18 are even, and 6 are odd but multiples of 3.
Therefore, the probability is:
P = (18 + 6) / 36
P = 24 / 36
P = 2 / 3

To find the area of rectangle, you multiple length by width, so that would be
Since we are talking about area \ length, x need to be positive so we don't need to worry about absolute value now.
#22
The area of triangle is
, so that would be
Hope this helps.
