Answer:
C. 42x² - 3x - 9
Step-by-step explanation:
Area:
(7x + 3) (6x - 3)
7x(6x - 3) + 3(6x - 3)
42x² - 21x + 18x - 9
42x² - 3x - 9
Answer:
? = 57
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos ? = adj/ hyp
cos ? = 14/26
Taking the inverse cos of each side
cos ^-1 ( cos ?) = cos ^-1 ( 14/26)
? = 57.42102961
To the nearest degree
? = 57

Hi there!
Everything looks correct except for the step to get to -6x < 36. Here you put multiplication property of order, and to get here you have to add 30 to both sides, so it would actually be the addition property of order.
I hope I helped!
As an improper fraction, the simplified answer would be 9/7 after you divide both top and bottom by 10
------------------------
If you need a mixed number, then 9/7 converts to 1 & 2/7 because
9/7 = 1 remainder 2
If you had 9 cookies and 7 friends, then each friend gets 1 whole cookie, and there will be 2 left over.
