**Answer:**

153 in²

**Step-by-step explanation:**

<h3> Area of irregular figure</h3>

Figure I:

length = 12 in

width = 6 in

Area of figure I = 12 * 6

= 72 in²

Figure II:

length = 13 in

width = 5 in

Area of figure II = 13 * 5

= 65 in²

Figure III:

side = 4 in

Area of figure III = 4 * 4

= 16 in²

Area of irregular shape = 72 + 65 + 16

= 153 in²

900 is indeed 1/10 of 9000, so **true**.

I think -5 is the right answer

9x^5 • 4x^4

9•4= 36

X^5+4= x^9

Your answer is 36x^9
