Length of the rectangle (l) = x + 5

Perimeter of the rectangle = 4x + 14

Formula of perimeter of the rectangle = 2(length + width)

Let the width of the rectangle be 'w'. So,

\rm \longrightarrow 2(l + w) = 4x + 14 \\  \\  \rm \longrightarrow 2(x + 5 + w) = 4x + 14 \\  \\  \rm \longrightarrow  \dfrac{2(x + 5 + w)}{2}  =  \dfrac{4x + 14}{2}  \\  \\  \rm \longrightarrow x + 5 + w = 2x + 7 \\  \\  \rm \longrightarrow x + 5 + w - (x + 5) = 2x + 7 - (x + 5) \\  \\  \rm \longrightarrow x - x + 5 - 5 + w = 2x - x + 7 - 5 \\  \\  \rm \longrightarrow w = x + 2

\therefore Width of the rectangle (w) = x + 2

a pipeline is laid at a rate of 1/8 mile per day.How many miles of line would be completed in 29 1/2 days​
Setler [38]

Answer:

In 29  1/2 days, the total pipe laid is (\frac{59}{16}) mile.

Step-by-step explanation:

The length of pipe laid in 1 day = 1/8 mile

So, the length of pipe laid in half day = half of (1/8 mile)

= \frac{1}{2}  \times \frac{1}{8}  = \frac{1}{16}  \textrm{mile}

Now, 29 1/2 days on simplification means 29 and half day.

So, length of pipe in 29 days = 29 \times \frac{1}{8}  = \frac{29}{8} mile

Now adding the length laid in half day = \frac{29}{8}  + \frac{1}{16}  = \frac{29 (2) + 1}{16}  = \frac{59}{16}  \textrm{mile}

So, in 29  1/2 days, the total pipe laid is (\frac{59}{16}) mile.

A rectangular swimming pool is 15 feet long and x feet wide. What is the perimeter when x=12 feet
Arisa [49]

Answer: 54 square feet

Step-by-step explanation:

To find perimeter of a rectangle we must use the formula l+l+w+w=p where l and w represent width and length

Since we know length and width is x=12 just substitute so

15+15+12+12=54 so 54 is the perimeter
