"three times a number" can then be written as  3 n .

3 n  "added to 4" can this be written as  4 + 3 n

"the number plus 7" can be written as  n + 7

The length of a rectangle is four times its width. if the perimeter of the rectangle is 80yd, find its length and width.
Vedmedyk [2.9K]
The length is 8. the width is 32. 

32(2) = 64

8(2) = 16

64+16 = 80 

So the length would be 8 and the width would be 32 since it's 4 times the length.

Hope this helped!

How many zero arin the product of any whole. number less than 10 and 500
Stolb23 [73]

Answer:

Hay un máximo de tres ceros en el producto de un número distinto de cero cero menor que 10 y 500

Para poder ver esto, la forma más fácil para resolver este problema es multiplicar todos los números entre 1 y 9 por 500, es decir:

01*500 = 500

2*500 = 1.000

3*500 = 1.500

4*500 = 2.000

5*500 = 2.500

6*500 = 3.000

7*500 = 3.500

8*500 = 4.000

9*500 = 4.500

Como vemos, si multiplicamos a 500 por cualquier número par, entonces obtenemos un número con tres ceros, mientras que si este es impar solamente obtenemos dos ceros
