x
3
−
150
=
66.
x3−150=66. The table shows the students’ answers.



Which statement is true?


Student
1
1 is correct because
72
3
−
150
=
66.
723−150=66.Student 1 is correct because 72 cubed minus 150 is equal to 66 point

Student
2
2 is correct because
6
3
−
150
=
66.
63−150=66.Student 2 is correct because 6 cubed minus 150 is equal to 66 point

Student
3
3 is correct because
18
3
−
150
=
66.
183−150=66.Student 3 is correct because 18 cubed minus 150 is equal to 66 point

Student
4
4 is correct because
7
3
−
150
=
66.
73−150=66.Student 4 is correct because 7 cubed minus 150 is equal to 66 point

Answer 1

Add and subtract polynomials of degree one and degree two What is the value of 3s3t−2 for s = 2 and t =−3 Method 1 Simplify first.

Answer 2

Student 2 is correct because 6 cubed minus 150 is equal to 66

Explanation:

`x^3-150=66`

`\implies x^3=66+150=216`

`\implies x=\sqrt[3]{216} =6`
