Answer: C 20
Explanation: Plug in 2 for k.
2^2 - (2-10) + 4(2) = 20
The value is 11.
121^1/24 is actually square of 121^1/12
so x= square of 121 = 11
Answer:
x = 7
Step-by-step explanation:
if ABC ~ DEF than AB ~ ED, AC ~ DF, and CB ~ FE
The ratio of AB to ED is given as 5/30 = 1/6
For AC ~ ED the ratio would be same x/42 = 1/6 cross multiply it
6x = 42
x = 7
