Answer:
63 m

63 m
Theres no real name for a shape with uneven sides. I just realized that. A four sided figure is a quadrilateral. Or irregular polygon/quadrilateral. A four sided shape with no even sides.
Answer:
f(3) = 16
Step-by-step explanation:
f(x)= 7x-5
We want to find the value when x=3
f(3) = 7*3 -5
f(3) = 21-5
f(3) = 16
(-2/5)-(-1/8)
Need to make the denominators the same
(-16/40)-(-5/40)
Multiply -2/5 by 8
Multiply -1/8 by 8
-- sign= positive
-16/40+5/40
Answer=-11/40
