X=3/2, -5 is that what u are asking for
we have the numbers
we know that
The sum of a number and its additive inverse is 0
so
therefore
the number n is equal to 
the sum is equal to zero
the answer Part a) and Part b) in the attached figure
Answer:
It is a solution
Step-by-step explanation:
To check and see if it is a solution, we can substitute it in
-16 +2(-24) = -64
-16 -48 = -64
-64=-64
Since this is true, it is a solution
Answer:
A=32
Step-by-step explanation:
Area of a trapezium=1/2(a+b)h
A=1/2(6+10)4
A=1/2(16)4
divide 16 by 2
A=(8)4
open the bracket
A=32
Check/ verify
A=1/2(a+b)h
32=1/2(6+10)4
32=1/2(16)4
divide 16 by 2
32=(8)4
32=32.
I hope this hopes?
