Answer:
7
Step-by-step explanation:
x +4+2x+1+3x-2 = perimeter of triangle.
(6x +3)ft = perimeter
given perimeter = 45feet
hence,
6x + 3 = 45
6x = 42
x = 7

Answer:
y=-4/3x-8/3
Step-by-step explanation:
Use the slope formula y2-y1/x2-x1 
Finding the slope, 4-(-4)/-5-1 = 8/-6 = -4/3
y=-4/3x + b
Substituting,
-4=-4/3+b
-12/3+4/3=b
b=-8/3
y=-4/3x-8/3
