7b^2 - 19b + 10
(b - 2)(7b - 5)
b1 = 2 ; b2 = 5/7
Yeah I’m also not %100 but I agree with the first person, #3
Answer:
x > 6 and x ≤ 10
Step-by-step explanation:
You have to sleep for more than 6 hours, which means it is greater than and can not be equal to because it has to be more than 6 hours.

Answer:
The three consecutive integers are 42,44 and 46
Step-by-step explanation:
n-2 n and n+2. n=44
or
(X) + (X + 1) + (X + 2) = 132
X + X + 1 + X + 2 = 132
3X + 3 = 132
3X + 3 - 3 = 132 - 3
3X = 129
3X/3 = 129/3
X = 43
43 + 44 + 45 = 132
