55+(x+25)=180
55+x+25=180
25+55+x=180
80+x=180
x=180-80
x=100
The answer is 42 cause you do ( 18*28=12x) wich is 504=12x which equals 42
Remember previous range was from -1 to 1
now multiply it by -5
range is from 5 to -5
answer is first otpion
V= 1/3π*r^2*h
⇒ 142 cm^(2)= 1/3π*r^(2)*(8.5 cm)
⇒ ...
⇒ r= 3.994.
Rounded to the nearest centimeter, the final answer is 4 cm.
Hope this helps~
