∑ Hey, KLPJDP615 ⊃

Answer:

x = 6 or x = -10

Step-by-step explanation:

Given:

Solve for x.

1 + |2+x|= 9

O x = 4 or x = -8

O x = 7 or X = -11

O x = 5 or x = -9

x = 6 or X = -10

Solve:

1 + |2+x|= 9

Subtract 1 from both sides:

1 + |2 +x| -1 = 9-1

Simplify

|2 + x | = 8

Applying absolute value rule: If |u| = a, a > 0 then u = a or u = -a

2 + x = -8

2 + x = 8

Solving:

2 + x = -8

2 - 2 + x = -8 - 2

x = -10

Solving:

2 + x = 8

2 - 2 + x = 8 - 2

x = 6

Hence, x = 6 or x = -10

Answer:

12.0 cm

Step-by-step explanation:

The Pythagorean theorem applies:

(12 cm)² +b² = (17 cm)²

b² = (289 -144) cm² = 145 cm²

b = √145 cm ≈ 12.04 cm

b ≈ 12.0 cm . . . . rounded to 1 decimal place
