Can anyone me do the question that are circled with red? you don't need to do the graphing calculator thing,, just factor them and do the chek. if u can't do the checking it's ok. p

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)

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

180
