Without any extra conditions, the answer could be 3, and the simplest polynomial with the given roots would be
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> + 4<em>i</em> )
= <em>x</em> ³ + 4<em>x</em> ² + (11 - 4<em>i</em> ) <em>x</em> + 80 - 2<em>i</em>
<em />
If the polynomial is supposed to have only <em>real</em> coefficients, then any complex roots must occur along with their complex conjugates:
(<em>x</em> + 5) (<em>x</em> - (1 + 4<em>i</em> )) (<em>x</em> - (1 - 4<em>i</em> )) (<em>x</em> + 4<em>i</em> ) (<em>x</em> - 4<em>i </em>)
= <em>x</em> ⁵ + 3<em>x</em> ⁴ + 23<em>x</em> ³ + 133<em>x</em> ² + 112<em>x</em> + 1360
and then the degree would be 5.

Answer: 504 cm^2
The surface area of the shape is:
3 3 * 3=9
9 * 7=63
63+9=72 * 7
=504cm^2
Answer:
Prime numbes
Step-by-step explanation:
Numbers whose only factors are 1 and itself are called prime numbers.
Such numbers have only two factors.
Examples are: 2, 3, 5, 7 ,9... etc.
