Let L be length and W be width
The perimeter of a rectangle is 2W+2L=36
Thus 2W=36-2L, W=18-L
Area of a rectangle is WL=80
Thus (18-L)(L)=80
18L-L^2=80
L^2-18L+80=0
(L-8)(L-10)
Thus L can either be 8 or 10.
Because WL=80
If L is 8, then W=10
If L is 10, then W=8
So either way, the notebook is 8 by 10
Correct me if I’m wrong but I believe the answer is 48
The value of x is a number :)
Answer:
<em><u>1</u></em><em><u>.</u></em><em><u> </u></em><em><u>A cross section is the new face you see when you slice through a three-dimensional figure. For example, if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section.</u></em>
The 3rd one because you have to get the y-intercept also which is -6
