Answer:
23 x + 62
Step-by-step explanation:
Simplify the following:
5 (4 x + 12) + 3 x + 2
5 (4 x + 12) = 20 x + 60:
20 x + 60 + 3 x + 2
Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):
(20 x + 3 x) + (60 + 2)
20 x + 3 x = 23 x:
23 x + (60 + 2)
60 + 2 = 62:
Answer: 23 x + 62
(-2)^2 actually equals 4
-2×-2=positive 4. :)
x=84
Add up all the sides and then subtract that number by the original amount of degrees. 540
Since she spends 30 minutes/day walking, the total number of minutes can be represented by 30 minutes for each day or 30*amount of days=30*d
