Step-by-step explanation:
25. (+10)-(-6) = 10+6 = 16
26. (-14)-(+7) = -14-7 = -21
27. (-3)-(-9) = -3+9 = 6
28. 0-(-9) = 0+9 = 9
29. (-3)-(+6) = -3-6 = -9
30. (+8)-(-9) = 8+9 = 17
31. (+13)-(+7) = 13-7 = 6
32. (-6)-(-12) = -6+12 = 6
The solution that makes both equations true is 'a', or (2,0), because if you substitute the 2 with the x and the 0 with the y, and solve both equations, you get the same answer. Also, you could try a graphing software, like desmos.
0=-2(2)+4
-4+4
0=0
0=(2)-2
0=0
P= 2(7+4)
P= 2(11)
P= 22
Final answer: 22 units

5 7/12
The area of a rectangle is shown through length times width. Being so, 13.7 times 10.5 equals 143.85 m^2.
