Answer:

42

Step-by-step explanation:

Let the missing length be represented as "x".

Based on the angle bisector theorem, we have the following equation:

x/21 = 30/15

x/21 = 2/1

Cross multiply

x*1 = 2*21

x = 42

Missing length = 42

Help me with the steps for y = 4x + 2 please.
Aleks04 [339]
You are correct. 4 is the slope and 2 is the y intercept. 

Reasoning:

y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept

In your case, m = 4 and b = 2.
