I only did the first part but maybe later I will solve the rest too. If there are any errors but tell me so I can update the pic.
The area of a rectangle is <em>L x W</em>. We have to get the value of x first so that we can find the area of the rectangle.
To get the value of x
given:
<span>a. 12 & X
b. X-2 & 16 </span>
solution:
12x (x) = (8-2 ) 16
12x = 16x-32
32 = 16x-- 12x
<u>32 </u> = <u>4x</u>
4 4
8 = x
Checking:
a. 12 & X b. X-2 & 16
Area of a rectangle = L x W Area of a rectangle = L x W
=12 x 8 = (8-2) 16
Area of a rectangle = 96 = 6 (16)
Area of a rectangle = 96
This is easy are you even in highschool lol jk its 12*16 becuase their are 16 rows and r represents the rows SO 192 BOOKS <==== Answer.
Ellipse is your answer, because if you plug the equation into a graphing calculator and identify the conic, the term ellipse is given-
Hello!
A number line usually doesn't say, 
,3.1567....., 3.8. Usually number lines do not use fractions either. They usually just may say, -1,0,1,2,3,4.. which are all integers.
Therefore, our answer is B) integers.
I hope this helps!
