Hello,
Assume Ax+By+Cz+D=0 the plane 's equation.
p=(0,0,0)==>A*0+B*0+C*0+D=0==>D=0
q=(0,1,0)==>A*0+B*1+C*0+0=0==>B=0
r=(1,2,3)==>A*1+0*2+C*3+0=0==>A=-3C
Let C=1==>A=-3
An equation of the plane is -3x+z=0
Answer:
1 cup of sugar per 2 cups of flour
Step-by-step explanation:
Well, you could tackle the rectangle first; it doesn't really matter what order you go in, as long as you get the final answer.
1) I'll start with the rectangle. Area=base x height, so 10*4=40
2) The top triangle will go next. Area=(base x height) divided by two. 4*10=40
40/2=20
3) Bottom triangle. 3*10=30
30/2=15
4) Add all areas together: 40+20+15=75
The total area is 75cm².
Hope this helps!
