Need asap. choose the expression that represents a cubic expression.

2x + 11
−3x2 − 2x + 11
4x3 − 3x2 − 2x + 11
5x4 + 4x3 − 3x2 − 2x + 11

The answer is  C 4×3 - 3×2 -2x + 11

Step-by-step explanation:

Hope this helped

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: 48
