Simplify the expression.

x^3-(x^2-3x)(x+3)

Simplify the expression.

3x3−5x2−16x+12

Step-by-step explanation:

Hope this helps you :D

9x

Step-by-step explanation:

x^3*-1(x^2-3x)(x+3)

      (-x^2+3x)(x+3)

distribute

x^3 - x^3-3x^2+3x^2+9x

x^3-x^3+9x

=9x

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
