Answer:
Total distance = 30.3 units
Step-by-step explanation:
Coordinates for the location of Alanah, Mia, Teresa and Arena are,
Alanah → (2, 8)
Mia → (8, 16)
Teresa → (8, 2)
Arena → (14, 4)
Distance between two points and is given by the formula,
d =
Distance between Alanah and Mia =
=
= 10 units
Distance between Mia and Teresa =
= 14 units
Distance between Teresa and Arena =
=
= 6.3 units
Total distance of Alanah's trip to Arena = 10 + 14 + 6.3
= 30.3 units

Answer:
Explanation:
The problem we are given is
We can write the square root of a fraction as a fraction with a separate radical for the numerator and denominator; this gives us
We can write the whole number 4 as the fraction 4/1; this gives us
We now need to "rationalize the denominator." This means we need to cancel the square root in the denominator. In order to do this, we multiply both numerator and denominator by √(2x); this is because squaring a square root will cancel it:
When multiplying radicals, we can extend the radical over both factors:
