Answer:
Step-by-step explanation:
-(m - 6) = 3m + 14
-m + 6 = 3m +14
Subtract 6 from both the sides
-m + 6 - 6 = 3m + 14 - 6
-m = 3m + 8
Subtract 3m from both the sides.
-m - 3m = 3m + 8 - 3m
-4m = 8
Divide by (-4)
-4m/-4 = 8/-4
m = -2

Are you asking to find the perimeter of the polygons?
Answer:
(a+2) Is your answer
Step-by-step explanation:
You could try synthetic division, but it's pretty complicated (not to mention for much harder problems), so you should try factoring this. What two numbers multiply up to 10 and add up to 7? Using trial and error, we would find these two numbers to be 2 and 5. Therefore, it factors into (a+5)(a+2).
The rectangle is 6·5 which is 30. The triangle is a little harder but just has one extra step. The length is 6 and the height shown is 2. The figure is only half of a rectangle though because it's a triangle, so you divide by 2. Six times two= 12. Divided by 2 equals 6. Now add to find the total. 30+6= 36 units squared.
