Answer:
16/21 dresses
Step-by-step explanation:
3/4 · k hours: 4/7 · k dresses for any constant k
If we want 1 hour, then k will need to be 4/3
4/3 × 4/3 hours: 4/7 × 4/3
1 hour = 16/21 dresses
Answer:
(2 x - 3)^2 thus it's True
Step-by-step explanation:
Factor the following:
4 x^2 - 12 x + 9
Factor the quadratic 4 x^2 - 12 x + 9. The coefficient of x^2 is 4 and the constant term is 9. The product of 4 and 9 is 36. The factors of 36 which sum to -12 are -6 and -6. So 4 x^2 - 12 x + 9 = 4 x^2 - 6 x - 6 x + 9 = 2 x (2 x - 3) - 3 (2 x - 3):
2 x (2 x - 3) - 3 (2 x - 3)
Factor 2 x - 3 from 2 x (2 x - 3) - 3 (2 x - 3):
(2 x - 3) (2 x - 3)
(2 x - 3) (2 x - 3) = (2 x - 3)^2:
Answer: (2 x - 3)^2
Hello!
So you need to find the sin of the angle:
sin20 = x / 10
10 x sin20 = x
x = 3.4
Hope this helps :))
