J represents the miles that Jessica rode. Since Jessica rode 9 miles farther, you must add 9 to the amount that roger rode.
<span>ab + bc + b</span>²<span> + ac =
(b</span>² + bc<span>)+(ab + ac) =
b(b+ c)+a(b + с) =
(b + c)(b + a)</span>
72 is a number between 67 and 113 that is a multiple of 3, 4, and 9.
72/3= 24
72/4= 18
72/9= 8
