Let the amount of shells collected by Aaron be
and the amount of shells collected by Maria be
respectively. Then the following system of equations should be solved:
First of all, express
out of first equation:
Then, replace
in second equation with found expression and solve it:
Finally, replace
in first equation with found value and solve it too:
So, Aaron has found
7 shells while Maria has found
21.
The formula in finding the sum or the total measure of the interior
angles of polygon having n sides is:
Sum of interior angles = (n – 2) 180
Where n = number of sides of the polygon
In this problem, you are asked for the sum of the interior
angles of a 17 sided polygon. You have to substitute the number of sides to the
formula:
Sum of interior angles = (17 – 2) 180
Sum of interior angles = (15) 180
Sum of interior angles = 2,700 degrees

Step-by-step explanation:
<u>1/2bc - 6ac + 2ab</u>
(1/2)(-1)(-3) - (6)(2)(-3) + (2)(2)(-1)
(1/2)(4) - (-36) + (-4)
2 + 36 - 4
34
<u>1/4(ac)² + 1/6ac</u>
(1/4)[(2)(-3)]² + (1/6)(2)(-3)
(1/4)(-6)² + (1/6)(-6)
(1/4)(36) + (-1)
9 - 1
