Which value of n makes the value of the expression 4n+3 a composite number is it a-1 b-2 c-3 or d-4

C )For n = 3 the expression 4n+ 3 is composite number.

Step-by-step explanation:

Given  : 4n + 3.

To find: Which value of n makes the value of the expression 4n+3 a composite number is it.

Solution : We have given  4n + 3.

Composite number : A composite number is a positive integer which is not prime (i.e., which has factors other than 1 and itself).

For, n = 3

4 (3) + 3

12 + 3

15 .

We can see 15 is not a prime number . it has factor 3 , 5, 15 .

So, For n = 3 the expression 4n+ 3 is composite number.

Therefore, C )For n = 3 the expression 4n+ 3 is composite number.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:
