The perimeter of a rectangle must be less than 172 feet. If the length is known to be 53 feet, find the range of possible widths
1 answer:
The interval notation for width of rectangle will be: (1,33)
Step-by-step explanation:
Perimeter of rectangle < 172 feet
Length of rectangle = 53 feet
Width of rectangle = ? (range of values)
The formula used to find perimeter of rectangle is:
where l is length and w is width
In our case we will use: because perimeter should be less than 172
Putting values:
So, width should be less than 33
Since width should be positive and greater than 0
So, the interval notation for width of rectangle will be: (1,33)

Answer:
<h2>Point P</h2>Step-by-step explanation:
9.59 is closer to 10 than 9, so we can safely say that points m and n cannot be correct. Point q can also not be correct, because it is to close to 10.
Therefore, answer is: Point P

Answer:
13
Step-by-step explanation:
Given x = 2, y = 3 and z = 4. We'll evaluate the value of x² + y² with given condition.
First, remind that we are only given the expression of x-term and y-term only and therefore, z-term is not included - it's not to be considered.
Substitute x = 2 and y = 3 in the expression:
Hence, the value of x² + y² when x = 2 and y = 3 is 13.
