To find :-
Solution :-
<u>According</u><u> to</u><u> Question</u><u>,</u>
- x = 3 + √8
- 1/x = 1/3-√8
- 1/x = 1(3+√8)/(3+√8)(3-√8)
- 1/x = 3+√8/3²-(√8)²
- 1/x = 3+√8/9-8
- 1/x = 3 + √8
<u>So </u><u> </u><u>that</u><u> </u><u>,</u>
- x² + 1/x²
- (x + 1/x)² - 2
- ( 3+√8+3-√8)²-2
- 9² - 2
- 81 - 2
- 79
Answer: She is correct that she can use a division expression.
It would be $4/(2/3) OR 4 ÷ 2/3 = cost per pound.
Not an easy division, but using the rule: invert the divisor and multiply.
4 × 3/2 = 6 So the cost is $6 per pound.
Step-by-step explanation: It would be easier to answer if the statements were included.
Using a decimal equivalent for 2/3, 4/0.667 is an easy division expression to solve on a calculator.
D. no definite shape or definite volume
