Answer:

Step-by-step explanation:
So we have the equation:

First, subtract 3 from both sides:

Definition of absolute value:

Divide both sides by 6 for both equations:

And we're done!
1c = 16t = x(

)
1c = 16t = 16 X 3
1c = 16t = 48

The height of the given trapezoid is 7.5 m.
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
Here
is the lower base length and
is the upper base length while h is the height.
Step 2:
In the given problem,
and
. Assume the height is h m.
The trapezoid's area 


So the height of the given trapezoid is 7.5 m.
Answer:
42
Step-by-step explanation:
We use (BODMAS) :
Brackets
Order/Index
Division
Multiplication
Addition
Subtraction
Now we do bracket first :
7(3²) = 7(9) = 63
Now we do division :
63÷3 = 21
Now we do multiplication :
2 × 21 = 42
