Answer:
x = 2 - 5
, x = 2 + 5
Step-by-step explanation:
x² - 4x = 71
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = 71 + 4
(x - 2)² = 75 ( take the square root of both sides )
x - 2 = ±
= ± 5
( add 2 to both sides )
x = 2 ± 5
then
x = 2 - 5
, x = 2 + 5
Answer:

Step-by-step explanation:
Answer:
B. 5 weeks
Step-by-step explanation:
Rearrange equation
6w = 34 - 4
Simplify equation
6w = 30
Divide both sides by 6 to make 'w' on its own
w = 5
