Answer:

Step-by-step explanation:
Hi there!
We want to find the distance between the points (2, -2) and (-4, 7).
To do that, we can use the distance formula.
The distance formula is given as
, where
and
are points
We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

Now substitute those values into the formula and solve


Simplify


Square the numbers under the radical

Add the numbers under the radical together

Simplify the square root

Hope this helps!
Answer:
E
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
8x + 15 is an external angle of the triangle, thus
8x + 15 = 3x + 20 + 4x + 5, that is
8x + 15 = 7x + 25 ( subtract 7x from both sides )
x + 15 = 25 ( subtract 15 from both sides )
x = 10
Thus none of them on the list → E
Well the ration would be 2:3 if that helps at all.
