Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
∠C = 180° - 45° - 65°
∠C = 70°
b/sin B = c/sin C
b/sin 65° = c/sin 70°
b = c/sin 70° × sin 65°
b = 20/0.9397 × 0.9063
b = 19.289
b = 19.3
Answer:

Step-by-step explanation:
Answer: B.x^3+4x^2-19x+14 is correct
Step-by-step explanation:
(x + 7)(x2 – 3x + 2)
Multiplying both
x^3-3x^2+2x+7x^2-21x+14
x^3+4x^2-19x+14
