Yes it is.A composite number is a one which has at least 1 factor other than 1 and itself.Since the given number,i.e.,13(7×11+1+2) is divisible by 13,hence it is a composite number(by definition). Hope it help you.#THANKS!
Yes it is a composite number because it is product of primes.As 7×11×13+13+13×2=13(7×11×1+1+1×2)=13(77+1+2)=13(80)=13×2×2×2×2×5
