Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.

Here, Old length of photograph = 5 inch

Old width of photograph = 7 inch

Now, length of new photograph = (5 + 2x) inch

width of new photograph = (7 + 2x) inch

Now, Area of frame with new dimension = Length X breadth

= (5+2x) X (7+2x)

= 5(7+2x) + 2x(7+2x)

= 35 + 10x + 14x + 4x²

= 4x² + 24x + 35

Thus, the expression for the area of frame is 4x² + 24x + 35.

Using Unit Rates to convert

miss Akunina [59]

Answer:

5 minutes

Step-by-step explanation:

To find the number of minutes it takes Jason to run a mile, we have to first find the rate at which he runs.

This is called Jason's speed. It is given as

$Speed = \frac{distance}{time}$

$Speed = \frac{440}{75}\\ \\\\Speed = 5.86 yards/second$

From the formula of speed, time is given as:

$time = \frac{distance}{speed}$

Time taken for Jason to run 1 mile (1760 yards) will therefore be:

$time = \frac{1760}{5.86} \\\\\\time = 300.34 secs$

Converting this time to minutes yields:

60 seconds = 1 minute

300.34 equals:

$\frac{300.34}{60} = 5.0 minutes$

It takes Jason 5 minutes to run 1 mile.
