Answer:
4th option
Step-by-step explanation:
x² - 2x - 3 = 0 ( add 3 to both sides )
x² - 2x = 3
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 3 + 1
(x - 1)² = 4
Answer:
n=6
Step-by-step explanation:
4n + 1= 25
Move constant to the right
4n=25-1
Calculate
4n=25-1
Then divide on both sides
Answer:
23 maybe because there is a 90 degree angle
5000 × .06 = $300 balance $5,300
5300 × .06 = $318 balance $5,618
5618 × .06 = $337.08 balance $5,955.08
5955.08 ×.06 = $357.30 balance $6,312.38
