Can someone help please ?

1. perimeter of Trapezoid = 35x+18

Option F is correct.

2. perimeter of square = 16x-32

Option C is correct.

3. perimeter of Pentagon = 10x-20

Option A is correct.

4. perimeter of Rhombus = 28x+8

Option H is correct.

Step-by-step explanation:

1. Trapezoid Perimeter

Side1 a: 9x+4

Side2 b: 7x+8

Side3 c: 12x-2

Side4 d: 7x+8

The formula used is:

Putting values and finding perimeter

So, perimeter = 35x+18

Option F is correct.

2. Square Perimeter

Side of square = 4x-8

The formula used is:

where a is side of square

Putting values in formula

So, perimeter of square = 16x-32

Option C is correct.

3. Pentagons perimeter

Side of pentagon= 2x-4

The formula used is:

where a is side of pentagon.

Putting values in formula

So, perimeter of Pentagon = 10x-20

Option A is correct.

4. Rhombus perimeter

Side of Rhombus=7x+2

The formula used is:

where a is side of rhombus

Putting values in formula

So, perimeter of Rhombus = 28x+8

Option H is correct.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
