Answer:
1071.2
Step-by-step explanation:
Mark as brainiest
1) place the compass needle on the external point r.2) make the compass width greater than the distance from r to the given line.
3) draw an arc cutting the given line at two points.
4) mark and label the points of intersection p and q.
5) without changing the compass width, move the compass needle to q and draw another arc below the line crossing the previous arc.
6) move the compass needle to p and make an arc below the line.
7) mark and label the point of intersection s.
8) draw a line from the external point r to the point where the arcs intersect, s.
9) line rs is perpendicular to line pq and passes through the external point r.
True, you can't simplify 1/2 any further
Answer:
The coordinates of the reflected triangle are 
, 
and 
.
Step-by-step explanation:
Let be a point 
, reflections across x- and y-axes are represented by the following operations:
x-Axis reflection:
y-Axis reflection:
If we know that 
, 
and 
, the coordinates after both reflections are, respectively:
The coordinates of the reflected triangle are , and .
Answer:
X^2 -4
Step-by-step explanation:
Not entirely sure but would u just expand the brackets. As this is a difference between 2 squares the answer should be correct but it not sure.
