Answer:
As shown in the attachment,
Step-by-step explanation:
Cramer's rule works as follows:
x+3y=16
3x+y=8
Then
x=Dx/D
y=Dy/D
where Dx,Dy,D are 2x2 matrices formed from of coefficients and right hand side.
D=
1 3
3 1
=1-9=-8
Dx=matrix D with first column replaced by the vector [16,8]=
16,3
8 1
=16-24
=-8
Dy=matrix D with second column replaced by the vector [16,8]=
1 16
3 8
=8-48
=-40
Therefore
x=-8/-8=1
y=--40/-8=5
Check:
x+3y=1+3(5)=16
3x+y=3(1)+5=8 ok.
Answer:
Well it would be 1 if 4b3c6 is what is actually given, but if it was (4b^3)(c^6) it would be 6 or if it was (4b)(3c^6), it'd still be 6
Answer:
i have tried but have no idea
help me too haha
Step-by-step explanation:
Answer:
The solid formed is a cylinder
The total surface area is 
Step-by-step explanation:
The given net is made up of a rectangle and two circles.
The total surface area is the area of the rectangle plus the area of the two circles.
This implies that:
The rectangular surface can be folded into the curved surface of a cylinder with the two circles becoming the lid.
