Prove that squaring a number will give a number that is divisible by 4
Marizza181 [45]
This is not true with every numbers, but here you need only one example, so it could be many, one of them are:

Proof:
Number 6, 
--Squaring of 6 = 6² = 36
--Now divide by 4, = 36/4 = 9  [ number is whole, so it is divisible ]

Number 8, 
-- Squaring of 8 = 8² = 64
--Now divide by 4, 64/4 = 16  [number is whole, so it is divisible ]

Here, I gave you two examples, but you can create some more, by any even number squaring like, 2, 4, 6, 8, 10, 12, 14

Hope this helps!

elena-14-01-66 [18.8K]
(x,y)
east is an increase in x
west is a decrease in x
north is an increase in y
south is a decrease in y

so
3 east (x+3)
1 block south (y-1)
6 blocks west (x-6)
5 blocks north (y+5)

so in total, x+3-6 and y-1+5
basically x-3 and y+4
minus 3 from  and add 4 to y
(1,-2)
(1-3,-2+4)
(-2,2) is the dropoff point

Very urgent....plz help!
Len [333]

Answer:

  none of the above. (Talk to your teacher about this question.)

Step-by-step explanation:

The differences between length and width are 4, 6, 12, so are not constant at either 4 or 6.

The ratio of width to length is 2/3, 2/3, 3/5, so is not constant at 2/3 or 3/2.

None of the answer choices (even after editing to add appropriate math symbols) describes the relation between length and width.
