Answer:
x =2, x = 4
Step-by-step explanation:
x^2 - 6x + 8 = 0
(x - 2)(x - 4) = 0
x - 2 = 0; x = 2
x - 4 = 0; x = 4
Answer:
46 hours
Step-by-step explanation:
1. add all the hours you've worked (41+49+48+46=184)
2. divide the sum by the number of weeks (184/4=46)
2 1/2 x 3 = 7 1/2 = 7 4/8
10 11/8
- 7 4/8
3 7/8
A is the correct answer
X² + 3x = 10
Convert to standard form.
x² + 3x - 10 = 0
factor x² = x * x
factor -10 = 5 * -2
(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0
x + 5 = 0 x² + 3x = 10
x = -5 -5² + 3(-5) = 10
25 - 15 = 10
10 = 10
x - 2 = 0 x² + 3x = 10
x = 2 2² + 3(2) = 10
4 + 6 = 10
10 = 10
Answer:
The terms are 9, 4, 3b and 7a.
