formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees
please mark brainliest
well, -12+7 is 5 times (23-7=16) so that answer is 80 and 6-(-5*4=-20) so that is also 16
Answer:

Step-by-step explanation:
Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

If the modulus function is positive then:

If the modulus function is negative then:

multiply through by -1

combining the resulting inequalities, the estimate of the possible range of heights will be 
Answer:
9x-2y=-17
becuase 7x+2x is 9 and y-3y is -2y and -11-6=-17
