A. 4y(2y + 5) = 4y(2y) + 4y(5) = 8y² + 20y
B. 7a(3a + 8b) = 7a(3a) + 7a(8b) = 21a² + 56ab
C. 13x³(3y + 2x²) = 13x³(3y) + 13x²(2x²) = 39x³y + 26x⁴ units²
D. 7m²(3m - 5) = 7m²(3m) - 7m²(5) = 21m³ - 35m² units²
Ok done. Thank to me :>
Answer:
25 males and 8 females.
Step-by-step explanation:
If x is the number of males and y = number of females we have the system:
x + y = 33
x - y = 17 Adding:
2x = 50
x = 25
so y = 33 - 25 = 8.
