Responder:
4n-1
Explicación paso a paso:
Dada la secuencia
3, 7, 11, 15, 19, 23 ..
El enésimo término si la secuencia se expresa como;
Tn = una + (n-1) d
a es el primer término = 3
n es el número de términos
d es la diferencia común = 7-3 = 11-7
d = 4
Sustituir
Tn = 3+ (n-1) (4)
Tn = 3 + 4n-4
Tn = 4n-1
Por lo tanto, el enésimo término de la secuencia es 4n-1
I think you meant simplify
Remove parentheses
5x*2+3x+4-2x*2+5x-1
Multiply the variables
10x+3x+4-4x+5x-1
Combine the variables
14x+4-1
Subtract
14x+3
Answer: D
Step-by-step explanation:
a^2 +b^2 = c^2
= 18
3\sqrt{2}^2= 18
18 + 18 = 36
The square root of 36 is 6
Answer:
The answer is 72
First you find E=180-130=50
Then you add all the angles and subtract from 360
102+100+50=252
360-252=108
then you do 180-108=72
Answer: 36 sec
Step-by-step explanation:
Let
x------> distance the kitten runs before being caught by the puppy
Remember that
The speed is equal to divide the distance by the time
v=d/t
solve for t
t=d/v
so
equate the time
x/20=(180+x)/25
25x=20(180+x)
25x=3,600+20x
25x-20x=3,600
x=3,600/5=720 m
t=d/v=720/20=36 sec
or
t=(720+180)/25=900/25=36 sec
