Answer:
A) sum = (180)(20) = 3600°
Step-by-step explanation:
The formula for the sum of interior angles for any polygon is (n-2) x 180° with n being the number of sides the polygon has.
We can just plug in 22 into the equation to get our answer:
(22-2) x 180°
= (20) x 180°
= 3600
Answer:
20
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = 3x² - 2 + 4x + 2 = 3x² + 4x
Substitute x = 2 into f(x) + g(x)
(f + g)(2) = 3(2)² + 4(2) = (3 × 4) + 8 = 12 + 8 = 20
For the first question the answer would be the first quadrant

Answer:
{2, 3, 4, 5, 6}
Step-by-step explanation:
You are expected to determine the digits of the given number, then list them between curly brackets. Even if a digit appears in the number more than once, you need list it only once. It is helpful to sort the elements of a set, but not necessary.
__
The digits are 5, 3, 2, 6, 4, 6.
In sequence, the unique digits are 2, 3, 4, 5, 6.
The set of digits in the number is ...
{2, 3, 4, 5, 6}
_____
"Roster notation" means you simply list the elements of the set.
The factors of 42 are: 1,2,3,6,7,14,21,42
