the correct answer for this is the last choice:
It is incorrect because the length of the unknown side is the square root of 7,225.
X-5+5x-12=25
x+5x=25+5+12
6x=42
x=42/6
x=7
Since the common difference is 6, we can assume that the sequence is arithmetic, with rule
T(n)=6n+5 where T(1)=11
T(9)=6(9)+5=59
Answer:
2/5÷1/6 = 2/1
Step-by-step explanation:
2/5÷1/6 = 2/5 times 6/1 = 12/5, 12÷2 is 6, 5 ÷ 5 is 1, so it's 2/1.
