Answer:
parallelograms
Area = base * height
Rhombus Area = Product of the diagonals
Trapezoid Area = median * height
For solving these equation, it is important to isolate the variable to then solve it.
In this first equation,
3(4+x)=x+6
12+3x=x+6
12+2x=6
2x=-6
x=-3
to prove this, just substitute x value back into equation;
3(4-3)=-3+6
3(1)=3
3=3
Same for the next equations;
1+2x-x=x-5+x
1+x=2x-5
1=x-5
6=x
Then substitute this value back into equation;
1+2(6)-6=6-5+6
1+12-6= 12-5
7=7
18 would count as a natural number, whole number, integer, ration number, and a real number. Basically everything listed except an irrational number.
