first number is 176 and second number is 126 both have a number of factors so there are not prime thus they are composite. for example 176can be written as 44X4. 22X8. 11X16. so it has many factors so 176 and 126 both are composite numbers

Heya!!
Here is your answer :-
We have to check whether 5×3×11+11 and 5×7+7×13 are composite numbers or not.
Ok first let's find out what are the two numbers : -
5×3×11+11
We will solve it according to BODMAS,
55×3+11
175+11
176
Yes this is a composite never because it has factors other than 1 that are 2,8 and 11.
Now let's find out the second number:-
5×7+7×13
According to BODMAS,
35+91
126
This is also an composite number because it has prime factors other than 1 that are 2,3, and 7.
Hope it helps you
