(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
Answer:
16
Step-by-step explanation:
4+4+7. Based on PEMDAS, this contain only addition, so go from left to right
4+4 = 8. Continue +7
8+7= 15. Then add 1.
15+1= 16.
Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
. - Thus, a total of 511000 cigarettes, as
. - Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as

- One year has 525600 minutes, thus the person loses 14 years of life, as

- Looking at the decimal part, the person loses 212 days of life, as

- Again looking at the decimal part, 22 hours, as

- Thus, the person loses 14 years, 212 days and 22 hours of life.

Answer:
y = 5
Step-by-step explanation:
AB = | 8 - (- 4) | = | 12 |= 12
Divide 12 by the sum of the parts of the ratio, 1 + 3 = 4
12 ÷ 4 = 3
Thus
y = 8 - 3 = 5
