Answer:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Step-by-step explanation:
-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)
10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)
Answer:
Yes anything under a C
Step-by-step explanation:
Refer to the diagram shown below.
The height of the pole is CD (3 m), and its shadow is AB (1.22 m).
The height of the building is h m, and its shadow is AD (38.5 m).
The two triangles ΔABC and ΔADE are similar because of AAA.
Therefore

Cross multiply.
1.22 h = 3*38.5 = 115.5
h = 115.5/1.22 = 140.91 m
Answer: 141 m (nearest meter)
