So x is from -3 to 10, including -3, but not including 10
so that would be the interval
[-3,10)
remember, the brackets [] are inclusive meaning ≤ and ≥
parenthasees () are not inclusive maning < and >
[-3,10)
We are given an expression 6x² + 6x +1 = 0 and we are asked what it the reason why the expression is not considered a perfect square. The answer is the letter "B" which is 6x² +6x +1. The number 6 is not a composite number.
Answer:
Monday - 4 hours
Wednesday - 14 hours
Step-by-step explanation:
'h' = hours worked on Monday
'2 + 3h' = hours worked on Wednesday
h + 2 + 3h = 18
4h = 16
h = 4 (Monday)
18 - 4 = 14 (Wednesday)
3x^2 + 3yx + 6xy +6y^2.
= 3x^2 + 6y^2 + 9 xy
The answer would be 0.4375 pounds
