Answer:
A rectangle and an equilateral triangle have the same perimeter
The perimeter of the rectangle is 2x+2(3x-1) inches
The perimeter of the equilateral triangle is 3(x+1) inches
Solve the value of x and the perimeter of each figure
10+18=28
17+11=28
OR
2x=28 where x=14
4x where x=7
Answer: The required scale factor of the dilation is 4.
Step-by-step explanation: Given that the parallelogram FGHJ was dilated and translated to form similar parallelogram F'G'H'J'.
We are to find the scale factor of the dilation.
From the graph, we note that
JH = 2 units and J'H' = 8 units.
We know that

Therefore, the scale factor of the given dilation is

Thus, the required scale factor of the dilation is 4.
Answer:
- 6.2
Step-by-step explanation:
The product of - 2 (3.1) is - 6.2.
Brackets mean to multiply so we have to multiply the - 2 by 3.1 which gives a result of - 6.2.
