Which best describes the structure of the expression (5 ⋅ 46.4) − (3.2 ⋅ 13.7)
aksik [14]
You are subtracting the results in the parenthesis.

I would go with a difference. 

Since 8 is being multiplied by 23.6 and -7.8, I would say product.

"A" is the best answer choice.

I hope this helps!

The length of a rectangular dog park is 50 feet. The width is half the length. Decide if each set of steps could be used to find
Leokris [45]

Answer:

4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes

Step-by-step explanation:

The length of a rectangular dog park is 50 feet. The width is half the length.

The formula for Perimeter is given as:

P = 2L + 2W

Length = 50 feet

Width = 50 feet/2

= 25 feet

P = 2(50) + 2(25)

P = 100 + 50

P = 150 feet

Hence, writing yes or no in front of each step in the options.

1. Find the Width by dividing 50 by 2. Then add the length and width and multiply the sum to find the perimeter = No

2. Find the Width by dividing 50 by 2. Then multiply the length by the width to find the perimeter. = No

3. Find the Width by dividing 50 by 2. Then add the length and the width to find the perimeter.= No

4. Find the Width by dividing 50 by 2. Then double the length, double the width, and add the products to find the perimeter = Yes

5. Find the Width by dividing 50 by 2. Then add the sum of each length and the sum of each width to find the perimeter = No

THE CORRECT STEP IN THE ABOVE OPTION IS OPTION 4
