Answer:

This is a 45 45 90 triangle, so v= $\sqrt{2}$ . The side opposite the right angle in a 45 45 90 triangle is equal to the length of the other sides * $\sqrt{2}$ .

Therefore, u=2, because $\sqrt{2}$ * $\sqrt{2}$ =2. So, your answer is A, 2.

Answer:

(15,-14)

Step-by-step explanation:

Given that,

The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).

Let (x,y) be the coordinates of point G. Using mid point formula,

$\dfrac{x+(-3)}{2}=6\ \text{and}\ \dfrac{y+6}{2}=-4\\\\x-3=12\ \text{and}\ y+6=-8\\\\x=15,\ \text{and}\ y=-14$

So, the coordinates of G are (15,-14).

Factor x^3−5x^2−25x+125

UkoKoshka [18]

(x-5)^2 . ( x+5)
=( x^2 - 10x + 25) . ( x+ 5)
=x^3 + 5x^2 - 10x^2 -50x + 25x + 125
= x^3 - 5x^2 -25x +125
