Answer:
2
Step-by-step explanation:
3x+15=21 (the opposite side of parallelogram is equal)
3x=21-15
3x=6
x=6/3
so x=2
AD=2
Answer:
2*2 is the number of people per car
5*4 is the toal number

The graph has a y-intercept of 2 and is shifted to the right 6 from the parent function.
The parent function, y=√x, looks like a parabola laid on its side. We generally only consider the positive square root unless told otherwise. Since we have √(x-6) instead of just √x, the graph is shifted to the right 6 units. The +2 at the end of the equation shifts the graph up 2.
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem, a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.

Let's assign the known values to the equation and solve for t.
h = 16t^2
86.4 = 16t^2
5.4 = t^2
2.323790008 = t
Rounding to the nearest tenth of a second gives 2.3 seconds.</span>
