Answer:
4x²y² + 20xy² + 25y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 2xy ; b = 5y
(2xy +5y)² = (2xy)² + 2*(2xy) * (5y) +(5y)²
= 2²x²y² + 2* 2* 5 * x*y*y + 5²*y²
=4x²y² + 20xy² + 25y²
31 dozen cookies = 372 cookies
372 cookies = 13 cups of flour
1 cookie = 13 ÷ 372 = 0.0349462365591 cups of flour
6 dozen cookies = 72 cookies
72 cookies = 0.0349462365591 x 72 = 2.516 cups
≈ 2.5 cups (nearest 1/4 of a cup)
