i would subtract 7 and divide by 4;
4x + 7 = 15
4x = 8
x = 2
Its c2= a2+b2
the 2 is supposed to be squared
The new player's personal time is 4.5 seconds.
<h3>What is the new player's personal time?</h3>
The first step is to determine the total time the 5 persons complete the dash.
Total time = 5 x 5.7 = 28.5 seconds
The second step is to determine the total time for the 6 people to complete the dash.
Total time = 6 x 5.5 = 33 seconds
The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds

To find the ratio of their perimeters, you need to know that the ratio of a perimeter is the square root of the ratio of the areas. (Area is 2 dimensional, so what you do to the perimeter will have twice or be squared for the area).
So, you would simplify the ratio of 18/32 to 9/16.
Then take the square root of 9 and 16 separately to find the ratio of the perimeters.
Square root of 9 is 3.
Square root of 16 is 4
So, the ratio of the perimeters is 3 in/4 in.
