Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
X = <span>width
2x-3 = </span><span>length
</span>
width = 6.5 m
length = 2x-3 = 2*6.5 - 3 = 10 m

Answer:
they are 16 and 4
Step-by-step explanation:
We can call the numbers x and y and we can write:
x - y = 12
x + y = 20
Adding these equations gives us 2x = 32 which means x = 16 and substituting this value into the first equation gives us y = 4.
Answer:
If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.
Hope this helps. :)
Step-by-step explanation:
Spanish:
Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.
De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.
Espero que esto ayude :)
