Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.

7x + 1    is composed by    + 7x       and       + 1

1 + 7x     is composed by      + 1          and      + 7x


So
7x + 1 = 1 + 7x

If RV = x+6, US = 5x-9, and RS = 11, find VT and ST
masha68 [24]

The values of VT and ST for the given rectangle are 13 and 23.56 respectively.

The given parameters:

  • <em>RV = x + 6</em>
  • <em>US = 5x - 9</em>
  • <em>RS = 11</em>

The value of VT and ST is calculated as follows;

<em>from the given </em><em>diagram </em><em>we can conclude the following;</em>

2RV = RT = US

2(x + 6) = 5x - 9\\\\2x + 12 = 5x - 9\\\\12 + 9 = 5x - 2x\\\\21=3x\\\\x = 7

RT = 2RV = 2VT = 2(7 + 6) = 26

VT = ¹/₂ x 26

VT = 13

The value of ST can be determined from Pythagoras theorem as follows;

ST = \sqrt{RT^2 - RS^2} \\\\ST = \sqrt{26^2 - 11^2} \\\\ST = 23.56
