please help me if possible ​

Answer 1

Answer:

7) Degree= 4

9) x = 3

Explanation:

7) (3x-3)(2x³+3x²)

—> 6x⁴+9x³-6x³-3x²

—> 6x⁴+3x³-3x²

Answer 2

6.A number on a number line is first represented by the length of a line segment, that is, by the distance from the origin ZERO to the point. Then the endpoint of the line segment is used to represent the number, instead of the length.

7.(3x−2)(2x3+3x2)

=6x4+9x3−4x3−6x2

=6x4+5x3−6x2

From the above it is clear that the given polynomial is of degree 4.
