7(2- 6x) = -196 I having trouble understanding this problem.

x = 5

Step-by-step explanation:

7(2 - 6x) = -196

14 - 42x = -196

14 - 42x - 14 = -196 - 14

-42x = -210

-42x/-42 = -210/-42

x = 5

Step-by-step explanation:

7(2 - 6x) = -195                Remove the brackets

7*2 - 7*6x = - 195

14 - 42x = - 195               Subtract 14 from both sides

-42x = - 195 - 14

-42x = - 209                    Divide by 42

x = - 209 / - 42

x = 4.976  

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
