Responder:
2 1/4 m; 225 cm
Explicación paso a paso:
Dado:
Cortar 9 metros en 4 partes de la misma longitud;
Por lo tanto,
9 metros / 4
= 2,25 metros
Por lo tanto, cada varilla será 2.25 = 2 1/4 m
En cm;
1 m = 100 cm
2,25 metros = x
x = 100 * 2,25
x = 225 cm
So the so the product of two consecutive numbers is 4160 or
x(x+1)=4160
distribute
x^2+x=4160
subtract 4160 from both sides
x^2+x-4160=0
find the factor (if you want to know how, just ask in the comments)
(x-64)(x+65)=0
so the answer is x could be 64 or -65
so the number that work are 64,65 and -65,-64
Answer:
If you are rounding to the nearest tens the smallest number is 45. If you are rounding to the nearest whole number, the smallest number is 49.5
