13. The relationship between the sum of the measures of the interior angles of a polygon, S, and the number of
sides of the polygon, it, is given by the equation
S=180(n - 2). The sum of the interior angle measures
of a certain polygon is 1.440. How many sides does
this polygon have?
A. 6
B. 8
C. 10
D. 12
E. 16

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
