Answer:
Step-by-step explanation:
To inscribe a circle in a given triangle PQR means to construct a circle in the triangle PQR. The incenter of a triangle is the midpoint in the triangle, which can be located by bisecting the three angles of the triangle individually.
The construction is shown in the attachment.
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
The following is an expression.

Step-by-step explanation:
1. The Two Rectangles Because Rectangles Are The Longest Shape In This Question.
2. You will have to draw it yourself i cannot draw on brainly.
3. Draw Again.
4. Draw Again..
5. Perimeter.
6. Rectangle
7. Rectangle because it's more longer so more people can sit with 1 table.
8. It would be a rectangle because they are sitting across from one another so they can talk face to face. The Circle is a good one to everyone is close and it's decorative.
Answer:
Q=91, S = 153
Step-by-step explanation:
QR and TS are parallel (see the arrows in the middle?). Means that angles T and Q add up to 180 - they are conjugate angles. Thus Q has to be 89 (since 89+91=180).
Same difference for R and S: they add up to 180 and since one is 27, the other has to be 153.
