Answer:
-3b³ - 5b² + 10b
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define Expression</u>
(10b + 7b² - 6b³) - (12b² - 3b³)
<u>Step 2: Simplify</u>
- Distribute negative: 10b + 7b² - 6b³ - 12b² + 3b³
- Combine like terms (b³): -3b³ + 10b + 7b² - 12b²
- Combine like terms (b²): -3b³ - 5b² + 10b

Q13.
1. Consider triangles ACB and DCE. In these triangles,
- given;
- given;
- as vertical angles (by vertical angles theorem)
Hence, triangles ACB and DCE are congruent by SAS postulate.
2. congruent triangles have congruent corresponding sides, so
Explanation:
If there are 7 options (7 tiles) but only 2 possibilities (2 tiles with the number one), our probability could be expressed as:
2/7 or 29% approximately for the first tile.
