The answer is 21
21x3=63 and 21x4=84
Answer:

Step-by-step explanation:
If two polygons are similar, then corresponding sides are in proportion.
The corresponding sides:
4 → x
y → 15
3 → w
2 → 6
z → 9
therefore:
<em>cross multiply</em>

<em>divide both sides by 6</em>

Function I’m just guessing?
X-intercept is (-3,0)
Y-intercept is (0,6)
The equation is y=2x+6
Replace y with 0 when solving for x-intercept and replace x with 0 when solving for y-intercept.
