Answer:
B
Step-by-step explanation:
Given
x² + 14x = 51
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(7)x + 49 = 51 + 49 , that is
(x + 7)² = 100 ( take the square root of both sides )
x + 7 = ± = ± 10 ( subtract 7 from both sides )
x = - 7 ± 10
Thus
x = - 7 - 10 = - 17
x = - 7 + 10 = 3

Answer:
- B. √96 in, √24 in, √120 in
Step-by-step explanation:
Use Pythagorean to verify:
The square of the two smallest lengths is same as the square of the largest side
- A. 108 + 72 = 180 ≠ 192, no
- B. 96 + 24 = 120, yes
- C. 132 - 24 = 108 ≠ 120, no
- D. 168 - 72 = 96 ≠ 84, no
Correct choice is B
