You should buy 106.25 ft 2, because if you multiply 8.5 times 12.5 you would get that answer, which is the area of the wall.
Answer: 18≤n≤38 is absolute value inequality for the problem.
Step-by-step explanation:
Given situation:- Half of a number n is at most 5 units from 14
that means the difference between 14 and half times n is less than 5

⇒18≤n≤38 is absolute value inequality for the problem.

Answer:
- 63 in the class
- (C+B)P' = 25
- (C+B+P)' = 18
Step-by-step explanation:
The number of students in the class is the total of all numbers on the diagram:
9 +5 +11 +6 +3 +4 +7 +18 = 63 . . . students in the 2015 senior class
__
Students taking Chem or Biology, but not Physics are those in the colored area, excluding those in the green:
9 +5 +11 = 25 science students not taking Physics
__
Students not taking science are those outside the colored areas:
18 students are not taking science
x = ± 3√6
2x² - 6 = x² + 48 ( subtract x² from both sides )
x² - 6 = 48 ( add 6 to both sides )
x² = 54 ( take the square root of both sides )
x = ± √54 = ± 3√6
