In this case, the parenthesis do not matter. the value of the equation remains the same with or without them. so you can rewrite this as y + 1 + 4, which is y + 5.

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!
