Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
#40: There are 40 people in the youth group. If you multiply 5 and 8 by 5 it equals 25/40 (the number going on the ski trip)
3 tens= 30
7 tenths= 0.7
8 hundredths= 0.08
so 30+ 0.7+0.08= 30.78
