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:
7
Step-by-step explanation:
43.96 divided by 3.14= 14 (diameter)
14 divided by 3= 7 (radius)
Answer:
1) yes--common difference is 3.
