Answer:
The correct answer is Option 2. 48
Step-by-step explanation:
The given equation is 3x² ---(1)
When we substitute the value of x we get the value of the equation.
Here it is given that,
x = 4
Substitute this value in the equation (1) we get,
3x² = 3*(4)² = 3*16 = 48
Therefore the correct answer is Option 2. 48
There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate
Look at equation 1,

this can quite easily be manipulated to show

.
Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one

which can then be solved for x since there is only one variable

and then with our x solution we can work out our y solution by using the equation we manipulated

.
So the solution to these equations is x=-2 when y=6
Ok
I need the question for this
You would divide 44 by 16 so the wing span is 2.75 ft.
6 inches because area= length times width and 6 times 8= 48 inches
