<u>Answer-</u>
The equation that describes the pattern is,

<u>Solution-</u>
P = Number of minutes Rodney spends practicing playing the piano
G = Number of minutes Rodney spends practicing playing the guitar
Taking P on x axis and G on y axis, the points are,

Taking first two points i.e  , the line equation will be,
, the line equation will be,






Putting the other two points i.e  in the equation, they also satisfy the equation. That means they are also on the same line
 in the equation, they also satisfy the equation. That means they are also on the same line  .
. 
From the result, it is evident that P and G are linearly related.

Answer:
x = 13
Step-by-step explanation:
6x + 14 + 4x - 8 + 2x + 18 = 180  {Angle sum property of tiangle}
6x + 4x + 2x + 14 - 8 +18 = 180 {Combine like terms}
                           12x + 24 = 180 {Subtract 18 from both sides}
                                   12x = 180 - 24
                                   12x = 156       {Divide both sides by 12}
                                      x = 156/12
 x = 13
