Answer:
For more wut -_-
Step-by-step explanation:
2x-3y <= 12
Subtract 2x from both sides:
-3y <= 12 - 2x
Divide all terms by -3 ( when you divide an inequality by a negative value you must also reverse the inequality sign)
y >= -4 +2/3x or can be written as y >=2/3x -4
It is so simple the total area for the polygon is equal to the sum of the areas of the 3 triangles. So the area = 15.9+17.5+19.6=15+17+19 +0.6+0.5+0.9
where 0.9+0.5+0.6=2
so the total area = 15+17+2+19=53 square units area.
Answer:
C. 50
Step-by-step explanation:
x+y=90
x=2y-30
90-y=2y-30
3y=120
y=40
90-40= 50
