Answer:

Step-by-step explanation:
Given
List of Options
Required
Which of the options has a degree of 2
The general format of a polynomial is

<em>Where n represents the degree </em>
In this case;
n = 2
Substitute 2 for n in expression above;





Comparing this format to the list of given options; the option with the same format is: 
Where
;
and 
<em>Hence, the polynomial with a degree of 2 is </em>
Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Answer:
I think the answer is: y = 0.5x^2 + 4x + 6, <3
