What do I need to solve :)
3^2 + 4^2 = 5^2
65/5=13
3x13 =39
4 x 13= 42
The expression that represents the number of days until only 10% remains is
T((d) 10%) = 100 • (1/2)^3.322
Answer:
x = - 3 ± 
Step-by-step explanation:
Given
4x² + 24x = 4 ( divide through by 4 )
x² + 6x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 1 + 9
(x + 3)² = 10 ( take the square root of both sides )
x + 3 = ±
( subtract 3 from both sides )
x = - 3 ±
