Answer:
step 1: 3x+x=56
step 2: 4x=56
step 3: x=14
Jessica is 14. Matt is 3 times her age so Matt is 42. 14+42 equals 56.

Step-by-step explanation:
Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165
Step-by-step explanation: sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .
C. 8k+17
in your expression you have:
(7k-4k+5k)+(13+10-6)=
=(8k)+(17)
