Hi!!
Could u please help me with this qs?
Factorize: (8-b)(3+b)
And please mention the property or identity to be used too

24 + 5b -b²

Step-by-step explanation:

i am not sure what is meant by propert/ identity but

8 x 3 = 24

8 x b = 8b

(-b) x 3 = (-3b)

(-b) x b = (-b)²

24 + 8b + (-3b) + (-b)²

24 + 5b - b²

24+4n≥60 so n≥9

Step-by-step explanation:

because 60-24 is 36 then 36 divided by 4 is 9 which mean she needs to work grader or equal to 9 hours
