Will odd numbers when added always make even numbers

1 answer:

8 0

Always. consider 2x which is always even (divisible by 2)

then 2x+1 is the form of all odd numbers.

add 2 of the odd numbers together to get (2x+1)(2y+1) = (4y² +2x +2y) + 1

the part in parentheses is always even can you see why? then adding one again always gives us an odd number.

Nimfa-mama [501]

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted
