13s - r^2; if r = 9 and s = 6
FromTheMoon [43]

Answer:

27

Step-by-step explanation:

r = 9

s = 6

r^2

= r x r

= 9 x 9

= 81

13s

= 13 x 6

= 108

13s - r^2

= 108 - 81

= 27

O is the midpoint of segment FG. FO=3x+17, OG=7x-15. <br><br><br> 98 points
AlladinOne [14]

O is the midpoint so both sides FO and OG need to equal each other.

3x + 17 = 7x - 15

Subtract 3x from both sides:

17 = 4x -15

Add 15 to both sides:

32 = 4x

Divide both sides by 4:

x = 32/4

X = 8

Now you have the value of X, solve for the lengths:

FO = 3x +17 = 3(8) +17 = 24 +17 = 41

OG = 7x -15 = 7(8) -15 = 56-15 = 41

Total length would be 41 + 41 = 82
