We can form this algebraic equation to work the equation out:
16 + 2x = -24
2x = -40
x - 20
Hope I helped.
Step-by-step explanation:
You are just replacing the 'n' with the number in the 'n box'.
So if this is the formula:

then:
B(-3)= 4-(-3/3)
B(-3)= 4-( -1)
B(-3)= 4+1
B(-3)= 5
B(0)= 4-(0/3)
B(0)= 4-0
B(0)= 4
B(3)= 4-(3/3)
B(3)= 4-1
B(3)= 3
They are all quadrilaterals <span />
