Answer:
Step-by-step explanation: Not completely sure but i think the answer is 11
For the first one: 1.14
Second one: 3.66
-b - 5x - 3 + 2b - 4x + 7....combine like terms
b - 9x + 4 <==
As follows
r-6=7
+6 +6
r= 13
First step is to plot all the given coordinates in the xy plane.
Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.
Formula to find the area of trapezium is:
Area = 
= 
=
= 5 * 5
= 25 square units.
So, third choice is correct.
Hope this helps you!
