If you have a TI-83 Plus calculator . You can go to 2nd X^-1 and use the matrices
Answer:
44cm^2
Step-by-step explanation:
(a+b)h/2
=(9+13)4/2
=22x4/2
=88/2
=44
The Area is 44 cm^2, so it's the first choice.
Your answer is 60 because you multiply 600 with .10 and get 60.00
Step-by-step explanation:

Distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2), all that you need to do is use the coordinates of these ordered pairs and apply the formula to those points. So the formula would be:D=square root symbol(X1-X2)2+(Y1-Y2)2. Hope I've helped you any
