Answer:

45

Step-by-step explanation:

x + x + 2x = 180      {Sum of angles of a triangle}

            4x = 180 {Divide both sides by 4}

              x = 180/4

x = 45

Match the polynomial expression on the left with the simplified version on the right.
Vitek1552 [10]

Given the following question:

First expression:

\begin{gathered} \frac{12x^3-14x^2+16x-8}{3x-2} \\ \text{ Factor the expression:} \\ 12x^3-14x^2+16x-8=2(6x^3-7x^2+8x-4) \\ \frac{2\left(6x^3-7x^2+8x-4\right)}{3x-2} \\ \text{ Factor:} \\ 2\left(6x^3-7x^2+8x-4\right)=(3x-2)(2x^2-x+2) \\ =(3x-2)(2x^2-x+2)=2\left(3x-2\right)\left(2x^2-x+2\right) \\ \frac{2\left(3x-2\right)\left(2x^2-x+2\right)}{3x-2} \\ \text{ Cancel the common factor:} \\ -(3x-2) \\ 4x^2-2x+4 \end{gathered}

IJ is a midsegment of FGH. IJ=10, FH=8, and GH=14.Find the perimeter of ijh
never [62]

Answer:

Perimeter = 21

Step-by-step explanation:

Given

IJ = 10

FH = 8

GH =14

Required

Calculate the perimeter of IJH

<em>See attachment for illustration</em>

From the attachment,

I = mid of FH.

So:

HI = \frac{1}{2} * FH

HI = \frac{1}{2} * 8

HI = 4

J = mid of GH.

So:

HJ = \frac{1}{2} * GH

HJ = \frac{1}{2} * 14

HJ = 7

Perimeter IJH is then calculated as:

Perimeter = HI + HJ + IJ

Perimeter = 4 + 7 + 10

Perimeter = 21
