<h3>Answer:</h3>
The 4th table: (rectangles, perimeter) = (1, 16), (2, 20), (3, 24)
<h3>Explanation:</h3>
The sums of the numbers shown in each figure are 8, 10, 12. In each case, this sum is half the perimeter of the figure, so the perimeter values are 16, 20, 24.
Only the 4th table shows these values for perimeter.
Answer:
1. Not a triangle

3. Triangle
4. Triangle
The answer is D. Because you use the foil method
Answer:
x = -3/8
Step-by-step explanation:
4(3 - 2x) = 15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 =15-12
-8x =3
Divide by -8
-8x/-8 = 3/-8
x = -3/8
The scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
<h3>Scale Factor of Similar Triangles</h3>
Scale factor of similar triangles is the ratio of their corresponding sides.
Given the two similar triangles in the diagram attached below, we have the following scale factor as:
Scale factor = 2/4 = 1/2
Therefore:
x = 1/2 × 9
x = 4.5 cm.
Therefore, the scale factor of the similar triangles is: 1/2. The value of x is: 4.5 cm.
