This would be easiest to do by completing the square.
x^2+10x-2=0
x^2+10x=2
x^2+10x+25=27
(x+5)^2=27
x+5=±√27
x=-5±√27
(x+5+√27)(x+5-√27)
Answer:
The answer for the question is -1.5
1) Answer is A (True). 5.7 can be written as fraction in which both numbers are whole finite numbers.
2) Answer is True. Explanation is same as for the previous question.
3) √24 is between 4 and 5. √16=4 and √25 is 5, therefore answer is D)
4) Answer is √136. 11²=121 and 12²=144 and the question doesn't include equal scenario which would look like "more or equal than 11 but less or equal than 12".
Answer:
I'm going to assume you meant 1.5 pounds and not 15 pounds each month.
