In a given rectangle, the longer sides are 7 units longer than the shorter sides. If we let the shorter sides be represented as
2 answers:
Answer:
Option D
Step-by-step explanation:
Given: The longer sides are 7 units longer than the shorter sides. The shorter side is x.
To find: Write an expression below that represents the perimeter.
Solution: It is given that the shorter side is x.
The longer side is 7 units longer than the shorter side. So, the longer side is
We know that the perimeter of the rectangle is
So, the expression for the perimeter
Hence, the expression for perimeter is .
So, option D is correct.

x = -4 is not undefined because f(x) = x+4 is in the top part, the numerator, not the denominator. So the value that makes f(x) = x + 4 zero does not result in a division by zero.
Indeed, if we try to evaluate (f/g)(-4), then we get
which does not involve a division by zero.
However, attempting to evaluate (f/g)(3) leads us to
which involves a division by zero, and divisions by zero are undefined
