So 30% of the 50 t-shirts need to be small.
You can just multiply the two together, to get 15 shirts that need to be small.
Long way: 30% = 3/10
1/10 of 50 is 5
1/10 * 3 = 3/10
5 * 3 = 3/10
15 = 3/10
Answer: 5
Step-by-step explanation: 120÷24=5. You can check by going 24 x 5 = 120
Your correct! That is the only answer that is responsible for that question!

Answer:
(x2 + y2) • (x + y) • (x - y)
Step-by-step explanation:
Trying to factor as a Difference of Squares :
1.1 Factoring: x4-y4
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : x4 is the square of x2
Check : y4 is the square of y2
Factorization is : (x2 + y2) • (x2 - y2)
Trying to factor as a Difference of Squares :
1.2 Factoring: x2 - y2
Check : x2 is the square of x1
Check : y2 is the square of y1
Factorization is : (x + y) • (x - y)
Final result :
(x2 + y2) • (x + y) • (x - y)
