The reason that would support that is ∠B ≅ ∠B , the reflective property of equality.
<h3>What are similar triangles?</h3>
Similar triangles are triangles that have their corresponding angles equal and the ratio of their corresponding lengths also equal.
Analysis:
triangle BDE and BAC share the same angle B
which means ∠DBE = ∠ABC.
The reflective property of equality says a number is always equal to itself. Therefore, ∠B ≅ ∠B

i) Plan A: 21/0,12 = 175 <min of calls>
Plan B: 15/0,14 ≈ 107 <min of calls>
=> 2 plans cost the same 107 min of calls
ii) The cost when 2 plans cost the same:
- Plan A: 107 × 0,12 = 12,84$ ≈ 13$
- Plan B: 107 × 0.14 ≈ 15$
Answer: i) 107 ii) A: 13$ B: 15$
Answer:
Step-by-step explanation:
1. Three zeroes equal 1,000
2. One zero equal 10
3. One zero equal 10
4. Look at the value without the zeroes
5. Three zeroes equal 1,000
6. Look at the value without the zeroes
7. Since 890 has one zero, one more zero equal 10
8. Look at the value without the zeroes
9. Same as 8.
10. Three zeroes equal 1,000
11. Look at the value without the zeroes
12. Three zeroes equal 1,000
13. Same as 11.
14. Same as 13.
15. N/A
16. I am not sure about this one cause I don't know if there are more zeroes or not, but same as 13.
Answer:
The answer is A.

Answer:
x² -3x - 54
Step-by-step explanation:
given roots of a polynomial are 9 and -6
this means that (x-9) and (x+6) are factors of the polynomial.
To get the polynomial with the least degree, simply multiply the two factors to obtain a quadratic expression (degree 2)
(x-9) (x+6)
= x² + 6x -9x -54
= x² -3x - 54
