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:
A = 9x² + 12x
Step-by-step explanation:
The area (A) of the rectangle is calculated as
A = height × width
= 3(3x² + 4x) ← distribute parenthesis by 3
= 9x² + 12x
Eighty seven written in standard form would be...
80 + 7 = 87
Good Luck! :)
Answer:
okay
Step-by-step explanation:
complementary angles are angles that add up to 90 degrees
so what you would do is take each number that you have and subtract it from 90
In the first one you would
1. take 90-80
2. you get your answer of 10!
i hope this helps :)
