She need 3 bags since the area of the triangle is base x height /2
Area 20*6=120
120/2=60
60/20= 3 since each bag covers 20m^2
Answer:
330.60.330.60.330.60.
Step-by-step explanation:
-30, 10*4=40 so you do 9-40+1 which is equal to -30
2x + 9 = -65
2x = -65 - 9
2x = -74
x = -74/2
x = -37
So, your final answer is -37
Hope this helps!
