Solve x in 2|x+ 6| + 9 = 19
2 answers:
Answer has two solutions: x = -11, x= -1
2|x+6| + 9 = 19
2|x+6| = 10
(Divide 2 on both sides to get rid of multiplication)
|x+6| = 5
|x+6| = 5
|x+6| = -5
Solving positive one first:
|x+6| = 5
x+6 = 5
x = -1
|x+6| = -5
x+6 = -5
x = -11
Answer has two solutions: x = -11, x = -1
Answer: x=-1
Step by step:
2|x+6|+9=19
Subtract 9 from both sides.
2|x+6|=10
Divide both sides by 2
|x+6|=5
Use the definition of absolute value.
x+6=5
Subtract 6 on both sides
x=-1

Answer:
Rounded, 22 yards.
Step-by-step explanation:
The pythagorean theorem states: a^2 + b^2 = c^2
a = 34, squared = 1156
b = 41, squared = 1681
Add those to get 2837.
√2837 = 53.26, rounded.
34 + 41 = 75
75 - 53 = 22
