Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
12). It moved up 2. If you look at each dot and count up 2 it’s where the new dot is.
Answer:

Step-by-step explanation:
Given

Required
Number of quarts in x gallon
This can be represented as:

So, we have:


Cross Multiply



fog(x+2) = f(g(x+2) = f ( x+2+7)
= f(x+9)
= x+9- 4
(f g)(x + 2) = x+5
