Answer:
30:80
Step-by-step explanation:
Because 300 divided by ten is 30 so 800 divided by ten is 80 :)
im not sure but I think it is b
hello ....
the equation of a plane that is ; ax+by+cz +d =0
the vector perpendicular to this plane is : V(a,b,c)
in this exercice ; a = -4 b= -4 c = -1
then: the equation of a plane that is ; -4x-4y-z +d =0
but the plane passing through the point (−2,−5,5) :
-4(-2)-4(-5)-(5) +d =0
23+d =0
d =-23
the equation of a plane is : -4x-4y-z-23 =0
4x+20+2x+6 is what you get when you distribute, just group the similar ones together and get 6x+26, that's the answer <em><u>6x+26</u></em><em><u /></em><u />
