Answer:
your finding the absolute value, I I this means absolute value which means if its negative it automatically is its own number you get rid of the negative sign if it's positive just keep it because it's already in it's normal number.
For example: I -4 I = 4
For example: I -5 I = 5
For example: I 3/4 I = 3/4
For example: I 3 I = 3
For example: I 4 I = 4
Area = 112cm^2
Step-by-step explanation:
Area = (a + b)*h / 2
M = (a + b) / 2
14 = (a + b) /
2*14 = a + b
28 = a + b
Area = 28*8 / 2
Area = 112 cm^2
31 Degrees
63+86= 149
180-149=31
9a - 2b
I hope this helps!
