Option B
Trevor isn't correct because -2i must also be a root
<em><u>Solution:</u></em>
For the polynomial with roots -7, 2i and 7 their roots can be,
1. ) Real roots
2.) Imaginary roots
The real roots are: -7 and +7
The imaginary root given is: 2i
The imaginary roots come from the square root. So they will be in form of
Therefore,
For f(x) with roots -7 and +7 and we have,
Fundamental Theorem of Algebra states that a polynomial will have exactly as many roots as its degree (the degree is the highest exponent of the polynomial).
So for f(x) with 4 roots, degree of f(x) is 4
So option B is correct. Trevor is not correct because –2i must also be a root.

Answer:
96cm²
Step-by-step explanation:
<u>Top left part:</u>
12 x 3 = 36 cm²
<u>Bottom right part:</u>
The width is 12 - 6 = 6, then 6 + 6 = 12, so
12 x 5 = 60cm²
<u>Add them together:</u>
60 + 36 = 96cm²
<u>Total:</u>
96cm²
Answer:
Will cost 123 dollars.
Step-by-step explanation:
Find perimeter (50 m)
50 meters = 164 ft
164/10 ft = 16.4 ft
16.4 ft x 7.50 = 123 Dollars
