Answer:
174 packages of t-shirts PLEASE GIVE BRAINLIEST
Step-by-step explanation:
139 x 5 = 695 t-shirts are needed
695 ÷ 4 = 173.75
Since you have to purchase whole packages of t-shirts you will need to buy 174 packages of t-shirts. 174 x 4 = 696 t-shirts
174 packages
The equivalent expression for (x + 4)^5 is 
The expression is given as:

To expand the expression, we make use of Pascal triangle, where:
5:= 1 5 10 10 5 1
So, we have:

Evaluate the exponents

Evaluate the products

Hence, the equivalent expression for (x + 4)^5 is

Answer:
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Step-by-step explanation:
Cos 2x+sin x
use Trigonometric identities.
cos (2x) = cos (x + x) = cos x cos x - sin x sin x
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
