Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units

Answer:
Quadrilateral has no Equal sides other than a Parallelogram.
Step-by-step explanation:
Step-by-step explanation:
the number line : a potentially infinite horizontal line.
it shows all numbers, with 0 in the center, eher we are looking at it. the negative numbers go to the left of 0, with -1, -2, -3, ... going from right to left.
the positive numbers go to the right of 0, with 1, 2, 3 going from left to right.
point S = -14
and the distance to a point R (RS) is 10.
now, on such a line we can always go in 2 directions : left and right.
our starting point is S (-14).
going 10 units to the right (positive direction) we get to -4.
as -14 + 10 = -4
going 10 units to the left (negative direction) we get to -24.
as -14 - 10 = -24
so, R can be at -4 or -24.
