Answer:
x = 9 ± √14
Step-by-step explanation:
x² − 18x + 67 = 0
Move the constant to the other side:
x² − 18x = -67
Take half of -18, square it, and add to both sides.
(-18/2)² = (-9)² = 81
x² − 18x + 81 = -67 + 81
x² − 18x + 81 = 14
Factor the perfect square:
(x − 9)² = 14
Solve for x:
x − 9 = ±√14
x = 9 ± √14
Answer: B and F I believe
Step-by-step explanation:
100 and 101
the two integers are n and n+1. this means that 2n+1=201. n=100 and n+1=101
Cost of paying someone to rake her yard for for years would be $80.
The leaf blower would cost $70.
So she would save $10 buy buying the leaf blower.
