Answer 1

Answer:

true

Step-by-step explanation:

if x is any integer then 4x+7 is always odd is true

Answer 2

Answer:

This statement is true.

Let's take 3 numbers as examples; 1,2 and 3.

1st situation = 4×1+7 = 4+7 = 11 (odd)

2nd situation = 4×2+7 = 8+7 = 15 (odd)

3rd situation = 4×3+7 = 12+7 = 19 (odd)

Thus, these are all odd numbers.

The reason behind it is that when we multiply any number by 4, it gives an even number; and when we add an odd number (7) to it, it gives an odd number.
