A-The perimeter of the new playground will be one-ninth the perimeter of the original.

B-The perimeter of the new playground will be one-third the perimeter of the original.

C-The perimeter of the new playground will be nine times the perimeter of the original.

D-The perimeter of the new playground will be three times the perimeter of the original.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
