Answer:
16. (4 + h)( 11 + h)
17. (2 - x)(20 - x)
18. (2 + x)(- 12 + x)
19. (6 + m)(- 7 + m)
20. x =4 and 3
21. x = 9 and -3
Step-by-step explanation:
16. 44 + 15h + h² = 44 + 11h + 4h + h² = (4 + h)( 11 + h) (Answer)
17. 40 - 22x + x² = 40 - 20x - 2x + x² = (2 - x)(20 - x) (Answer)
18. - 24 - 10x + x² = - 24 - 12x + 2x + x² = (2 + x)( - 12 + x) (Answer)
19. - 42 - m + m² = - 42 - 7m + 6m + m² = (6 + m)(- 7 + m) (Answer)
20. x² - 7x + 12 = 0
⇒ x² - 4x - 3x + 12 = 0
⇒ (x - 4)( x - 3) = 0
⇒ x =4 and 3 (Answer)
21. x² - 6x = 27
⇒ x² - 6x -27 = 0
⇒ x² - 9x + 3x - 27 = 0
⇒ (x - 9)( x + 3) = 0
⇒ x = 9 and -3 (Answer)
Hello!
The formula for area of a circle is
is 3.14 (which is 22/7), and r stand for the radius, which is half of the diameter. If the diameter is 28 cm, the radius is 14 cm.
616
Answer:
Approximately 616 cm

1 over 1/2 will simplify into 2. 2/1 simplifies into 2. All we are doing is just dividing by 2 on both the denominator and numerator. So if we want the 1/2 into a whole number, just multiply it by 2 on both sides which then you get 2/1 which simplifies into 2. So the answer is 2. Hope this helps and answers your question!
