Answer:
x = 175/7
Step-by-step explanation:
Combining the like terms in 4x-14+3x=161, we get
7x = 175, and so:
x = 175/7
Tan=o/adj
Tan=60/b
B=60/tan(68)

Answer:
s = - 1 ± 
Step-by-step explanation:
Given
s² + 2s - 6 = 0 ( add 6 to both sides )
s² + 2s = 6
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(1)s + 1 = 6 + 1
(s + 1)² = 7 ( take the square root of both sides )
s + 1 = ± ( subtract 1 from both sides )
s = - 1 ±
Thus
s = - 1 - , s = - 1 +
