Step-by-step explanation:
This is called direct propotion
it involves close multiplication
a. true
b. false ( angles should equal 180 125+65=190)
c. true
d. true
e. true
Add powers of 3.
1 + 3 = 4
4 + 9 = 13 = 4 + 3^2
13 + 27 = 40 = 13 + 3^3
40 + 81 = 121 = 40 + 3^4
Now you need to add 3^5 to 121.
121 + 3^5 = 121 + 243 = 364
