Answer:

According to transitive Property of equality :  If a =b and b = c then a = c

In this problem you are given with 2 equations:  

                                h(x) = - 2x + 5  ---- 1

                                h(x) = 3           ------ 2

Apply transitive Property of equality to equation 1 and 2

      - 2x + 5       =  3                     Now solve for x.  

      -2x  + 5 - 5   =  3 – 5           subtract 5 on both sides.

                   -2x  = -2                              

   (-2x)/(-2) = (-2) / (-2)        Divide with -2 on both sides.

              X = 1

Step-by-step explanation: I hope this helps.

Use the interactive tool to create the three-dimensional
Sati [7]

The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.

Step-by-step explanation:

The given is,

                 Detailed view or net diagram of the three dimensional diagram.

Step:1

                Three dimensional diagram of the given net diagram is attached.  

                From the three dimensional diagram given net diagram is rectangular prism.

Step:2

                 From the three dimensional diagram

                 Formula for surface area of the rectangular prism,

                                       A = 2(wl + lh + hw)..............................(1)

                 Where, w - Width

                                l - Length

                               h - Height

                 From the attachment,

                               l = 6 cm

                              w = 2 cm

                               h = 3 cm                

                 Equation (1) becomes,

                              A = 2((6)(2) + (6)(3) + (3)(2))

                                   = 2 ( 12 + 18 + 6 )

                                   = 2 ( 36 )

                               A = 72 squared centimeters

                                  ( or )

                 From the net diagram,

                 Surface area, A = ((6×3)+(2×3)+(2×6)+(2×3)+(3×6)+(2×6))

                                            = 18 + 6 + 12 + 6 + 18 + 12

                                            = 72

                Surface area, A = 72 squared centimeters

Result:

          The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.
