A = 2, B = -1, C = 3
-3a^2 - b^3 + 3c^2 - 2b^3
-3(2^2) - (-1^3) + 3(3^2) - 2(-1^3)
-3(4) - (-1) + 3(9) - 2(-1)
-12 + 1 + 27 + 2
-12 + 30

See the attached image below for the drawing.
Point G = midpoint of segment DE
Point H = midpoint of segment FD
---------------------------------------------------------------------------------
Add up the x coordinates of points D and E, then divide by 2. So you should get (x1+x2)/2 = (0+2)/2 = 2/2 = 1. This is the x coordinate of point G.
Repeat for the y coordinates of D and E. So we have (y1+y2)/2 = (7+0)/2 = 7/2 = 3.5
Therefore point G is located at (x,y) = (1, 3.5)
---------------------------------------------------------------------------------
These steps will be repeated to find the midpoint H
Add up the x coordinates of F and D, then divide by 2. So, (x1+x2)/2 = (6+0)/2 = 6/2 = 3
Do the same for the y coordinates: (y1+y2)/2 = (7+0)/2 = 7/2 = 3.5
Point H is located at (3, 3.5)
Answer: 6x + 14 cm
Step-by-step explanation:
side(1) of rectangle = x + 8
side(2) of rectangle = 2x - 1
perimeter of rectangle = 2(L+B)
=2(x + 8 + 2x - 1)
=2(3x + 7)
=6x + 14
therefore the perimeter of the rectangle is 6x + 14 cm
