Answer:

  • Not an isosceles trapezoid

Step-by-step explanation:

Plot the given points.

We can see and  visually confirm this is not isosceles.

<u>(1,1) to (3, 3) distance is:</u>

  • AD = \sqrt{(1-3)^2+(1-3)^2  } = \sqrt{8} = 2\sqrt{2}

<u>(5,3) to (8, 1) distance is:</u>

  • BC = \sqrt{(5-8)^2+(3-1)^2  } = \sqrt{13}

We see AD ≠ BC

The sides are not of the same length.

Answer:

8.333333

Step-by-step explanation:

 3x+2(4+6x)=133

  3x+8+12x=133                      First I distibuted the 2 too the 4 and 6x

15x+8=133                                 Then I added the x es 3x and 12x

15x+8-8=133-8                         Then I subracted 8 from both sides

15x=125                                    That leaves with this

 15x/15=125/15                          Now I divide 15 from both sides to isolate x

x= 8.33333                                 that is the answer

                             check

                  3x+2(4+6x)=133

                 3*8.333333+2(4+6*8.333333)=133

                  24.999999 +2(4+ 49.999998)=133

                    24.999999+2( 53.999998)=133

                         24.999999+107.999996=133

                              132.999995=133

                       

                                 You can not get an exact answer for this problem
