Answer:
25.
Step-by-step explanation:
I am assuming you only mean the small triangles, not the composite ones.
The second triangle set has 3 triangles on bottom row and 1 on the top - total 4.
The 3rd triangle set has 5 triangles on the bottom , 3 on the next up and 1 on the top - total 9
Following the pattern 4th set will have the number of triaNGLES
7 + 5 + 3 + 1 = 16.
So the 5th will have 9 + 7 + 5 + 3 +1 = 25 triangles.
A. 32/4=8
B. Square root of 9 = 3
Answer:
5=4

<em> 9(x + 2)</em>
- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6(x+4)+3(x−2) =</em>
<em>= 6x + 24 + 3x - 6</em>
<em>= 6x + 3x + 24 - 6</em>
<em>= 9x + 18</em>
<em>= 9(x + 2)</em>
<em>Good luck !</em>
