Use the midpoint formula to find the midpoint between H(3, 9) and J(9, -2).
TiliK225 [7]

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: (\frac{x_{1}+x_{2}} {2},\frac{y_{1}+ y_{2}} {2}).

With the formula above, we can substitute the given points into the equation, and simplify.

(\frac{3 +9}{2}, \frac{9+(-2)}{2}) = (\frac{12}{2}, \frac{7}{2}) = (6, 3.5)

Therefore, the midpoint between points H and J is choice D, (6, 3.5).

What is equation created from the sqrt(x+2)+2))^2
Naddika [18.5K]

Answer:

x + 4√(x + 2) + 6

Step-by-step explanation:

All we need to do is expand by using FOIL (First, Outside, Inside, Last):

x + 2 + 2√(x + 2) + 2√(x + 2) + 4

Then we combine like terms to get our final answer:

x + 2 + 4√(x + 2) + 4

x + 4√(x + 2) + 6
