Answer: True.

Step-by-step explanation:

True, the incenter of a triangle is the center of the only circle that can be inscribed in it.

Because, incenter is the point of intersection of the all the angle bisectors of the three angles of the triangle which divided the each angle into two parts.

Hence, the incenter is the radius of the only largest circle that can be inscribed in it.

Answer:

\large\boxed{x^3+x^2+2x^2y+2xy+xy^2+y^2}

Step-by-step explanation:

Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>

<em />

(x^2+2xy+y^2)(x+1)\\\\=(x^2)(x)+(x^2)(1)+(2xy)(x)+(2xy)(1)+(y^2)(x)+(y^2)(1)\\\\=x^3+x^2+2x^2y+2xy+xy^2+y^2

damaskus [11]

Answer:

middle brother = x

older brother = x+1

younger brother = x-1

x-1+x+x+1=129

3x+0=129

3x=129

x = 43(middle brother)

43-1 = 42(younger brother)

43+1 = 44(elder brother)

Check:

43-1+43+43+1=129

42+43+44=129

129=129

I think u guys know what to do !!!
kotykmax [81]

Answer:

B, C

Step-by-step explanation:

7 - x = 18

A.

7 - 2x = 18 - x

126 - 14x = 324 - 18x

We are nowhere near the solution.

B.

-x = 11

x = -11

This works.

C.

7 = x + 18

-11 = x

This works.

D.

25 - x = 36

-25 + x = -36

This does not help.

E.

7 = x + 18

0 = x + 11

We still do not have a solution.
