that's how I read it.... to get some value between 1 and 5, namely 4, to make the expression a rational, well, 48 can be expressed as 48/1.
Answer:
Perimeter of the rectangle is 16x+18 units.
Step-by-step explanation:
The area of rectangle is
First we have to find the factor form of above expression.
Splitting the middle term, we get
Area of a rectangle is the product of its dimensions. It means dimensions of the rectangle are (x+8) and (7x+1).
Perimeter of a rectangle is
Therefore, the perimeter of the rectangle is 16x+18 units.
B is the answer. It's any number that is less than 2 and -1 will become 1 because it's the absolute value.
