The value of x is 7.5.
<h2>Dilation</h2>
Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
The smaller triangle was dilated to form the larger triangle.
A smaller triangle has side lengths of 5, 13, 12. A larger triangle has side lengths of x, blank, 18.
<h3>To find </h3>
The value of x.
<h3>How to find the value of x?</h3>
We know the formula.
Side of a large triangle = Dilation x Side of a small triangle
Then we have,
18 = Dilation x 12
Dilation = 1.5
So the blank side will be
Blank side = 1.5 x 13
Blank side = 19.5
And x will be
x = 1.5 × 5
x = 7.5
Thus, the value of x is 7.5.

Answer:
322.19
Step-by-step explanation:
RECTANGLE AREA =L × B
=12 × 8
AREA OF CIRCLES= 4(1/2×PIE×6×6)
TOTAL AREA= 12 × 8+ 4(1/2×PIE×6×6)
=322

We need the list of scores first before we can answer :(
The perimeter when 96 triangles are put together in the pattern shown below will be 98cm
Find the required triangle attached
In the diagram shown, we can see that we have 5 triangles.
The first thing we need to do is add one more triangle to have, six triangles,
Perimeter of the resulting 6 triangles = 6 + 2 = 8cm
For 8 triangles;
Perimter = 8 + 2 = 10cm
For "n" triangles;
Perimeter of n triangles = n + 2
Hence if 96 triangles are put together in the pattern shown below, hence
n = 96
Perimeter of the 96 triangles = 96 + 2
Perimeter of the 96 triangles = 98 cm
Hence the perimeter when 96 triangles are put together in the pattern shown below will be 98cm
