Answer:

Yes, it is a rational number.

Step-by-step explanation:

A rational number is a number that can be expressed in fractional form. A rational number consists of:

Integers - they can be expressed in form of $\displaystyle{\dfrac{a}{1}}$ where a is an integer.

Fractions - obviously that they are in fractional form.
Repeating Decimals - they can be expressed in form of fractions as well.

Since the difference of 18 and 3 is 15 and the number 15 can be expressed as 15/1. Therefore, 15 or the difference of 18 and 3 is a rational number.

If a rectangle's length is 7 more than 4 times the width and the perimeter is 54 what are the dimensions of the rectangle?

Rus_ich [418]

Let w = width of the rectangle
4w+7 = length of the rectangle 

perimeter = 2 lengths + 2 widths 

2w + 2(4w+7) = 54 
2w + 8w + 14 = 54 
10w = 40 
w = 4 
4w+7 = 23 

dimensions of rectangle: 
width = 4 
length = 23 hope this helps
