It looks like the limit is

Factorize the numerator and denominator to reveal a removable discontinuity and evaluate the limit.

When choosing the shirts it doesn't matter what order they're chosen in because at the end you'll have the same four shirts ... so it's a combinations question (rather than a permutations question where the order of choice makes a difference)
<span>so number of groups = 6C4 = 15 </span>
<span>another way is to evaluate 6P4 / 4! = 360/24 = 15

Answer: x^2 + 5x = 0
Work: x(x + 5)
x(x) + x(5)
x^2 + 5x
Answer:
-16m^16 n^5
Step-by-step explanation:
(2m^4)^4*-n^5
= 2^4*m^16*(-n^5)
= 16 m^16 * (-n^5)
= -16m^16 n^5
hopefully this will help
