In order to find the values here, we start by setting the width equal to x. Now knowing this, we know that the length is twice that long. Therefore, the length would be equal to 2x. Now we can use the perimeter formula to solve the equation.

2L + 2W = P

2(2x) + 2(x) = P

4x + 2x = 36

6x = 36

x = 6

Now with the given value for x, we can tell that the width is 6 and then we multiply it by 2 to get the length value (12).

swati won a Computer game that she played with matt. The sum of the scores was 754. The difference of there scores was 176. How

klio [65]

<u>Answer:</u>

Swati - 465 , Matt - 289

<u>Explanation:</u>

Let Swati's score be x and Matt's score be y.

Since Swati won the game her score is obviously higher.

We are given the sum and difference between their scores which we can write as , x + y = 754 and x - y = 176.

Solving these two equations by adding them we get 2x = 930 so x = 465. Substituting x in x - y = 176 we get y = 289

Thus Swati scored 465 points and Matt scored 289 points.
