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.
200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 + 200 = 1,800
Answer:
SAS
Step-by-step explanation:
Becaus it is rectangle when we see it at the diagonal
The answer is 0.67, simply show your work subtracting then and you get that number, it’s basic subtraction, only you have to count the decimal points to put them in the correct spot
17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.
