Answer:

C. 7(x + 2) - 3x = 2/3 (6x + 3)

Step-by-step explanation:

ANSWER FROM PLATO

When solving an equation, if the variable terms cancel out leaving different numbers on each side of the equal sign, then the equation has no solution.

Consider the following equation:

7(x + 2) - 3x = 2/3 (6x + 3)

   7x + 14 - 3x = 4x + 2

     4x + 14 = 4x + 2

             14 = 2

Therefore, the equation  has no solution.

Yuliya22 [10]

Tanya run 50 yards across the diagonal of the rectangular field.

<u>Step-by-step explanation</u>:

Step 1 :

  • Length of the rectangular field = 40 yards
  • width of the rectangular field = 30 yards

Step 2 :

Measure of the diagonal = √(length^2 + width^2 )

Step 3 :

Diagonal = √(40^2 + 30^2 )

               = √(1600 + 900)

               = √2500

               = ±50

Step 4 :

Since distance cannot be negative, The measure of diagonal = 50 yards.

∴ Tanya runs diagonally across a rectangular field is 50 yards.
