The answer is c
(0,8) is the y intercept so the +.. is +8
then pug in 4 to x and find which one equal 0
Answer:
This means the dot IS a part of the solution.
Step-by-step explanation:
A closed dot means it is included, but an open dot means it is not included.

Answer: A) 57</h3>
==============================================================
Explanation:
For any convex polygon, the sum of the exterior angles is always 360 degrees.
The exterior angles (5x+12), (10x-37) and (9x+1) add to 360. Use this to solve for x.
(5x+12)+(10x-37)+(9x+1) = 360
(5x+10x+9x) + (12-37+1) = 360
24x-24 = 360
24x = 360+24
24x = 384
x = 384/24
x = 16
The expression 10x-37 is then
10x-37 = 10*16-37 = 160-37 = 123
which is the measure of the exterior angle adjacent to angle BCA
The last step is to subtract this from 180 to get angle BCA itself
angle BCA = 180 - 123 = 57
Perimeter=2(width+length)
72=2(9+L)
72=18+2L
2L=54
L=27YARDS
the garden is 27 yards long
