Answer:
C(-4,-2), D(3,-7)

Step-by-step explanation:
we procced to identify points:
A(-4,-7), B(3,-2)
for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH)
C(-4,-2), D(3,-7); Area of the rectangle Ar=b*h, where

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=
If you turn it around it would be easier like this......
m - 6 + -2m = 18 its really easy just find a number and place i there until u get the awnser
So, if there are 28 students desks, and each desk is 26.17 inches long...
You multiply 26.17 by 28, to see how long it is:
26.17 * 28 = 732.76
The answer to the question is 2.)2.5 because when you substitute 12/7 into the inequality you get 20 which is not greater than 20 and when you substitute -3 you get -13 which is also not greater then 20 but when you substitute 2.5 you get 25.5 which is greater than 20
