a) Xét △BAD và △EAD có:
∠DBA = ∠DEA = 90°
AD chung
∠DAB = ∠DAE( AD là p/g của ∠BAE )
=> △BAD = △EAD (g.c.g)

P(x)=(x3−x3)+(−2x2+2x2)+(5x−3x)+(−3+5)
P(x) = (\(x^3\) - \(x^3\)) + (-2 \(x^2\) + 2 \(x^2\) ) + (5x - 3x) + (-3 + 5)
P(x)=0+0+2x+2
P(x) = 0 + 0 + 2x + 2
P(x)=2x+2
b) Q(x)=x3⋅x+x3⋅(−3)+(−2\(x^2\) ).x+(−2\(x^2\) ).(−3)+5x⋅x+5x.(−3)+(−3)⋅x+(−3).(−3)
Q(x)=\(x^4\) −3\(x^3\) −2\(x^3\) +6\(x^2\) +5\(x^2\) −15x−3x+9
Q(x) = \(x^4\) - 3\(x^3\) - 2\(x^3\) + 6\(x^2\) + 5\(x^2\) - 15x - 3x + 9
Q(x)=\(x^4\) −5\(x^3\) +11\(x^2\) −18x+9

c)

Vậy nghiệm của đa thức P(x)là x=−1

1.a) A={0; 1; 2; 3; 4; 5; 6; 7; 8; 9}
b) B={2; 3; 5; 7}
\(\frac{4}{10}\) = 0,4 = 40%
2.a) Đông khách nhất: 11 giờ trưa
Ít khách nhất: 9 giờ sáng

b) Số lượt khách tăng là: 45 - 30 = 15 (khách)
