On a sketch of a mural,3 inches represents one foot in the mural. A door in the sketch is 2 inches wide by 5 inches high. What i
grandymaker [24]

Answer:

Length of the door,                  <em> l</em> = 5 inches (<em>in</em>)

Width or Breadth of the door, <em>w</em> = 2 inches (<em>in</em>)

Perimeter                                   p = 2(l + w)

                                                   = 2( 5 + 2) <em>inches</em>

<em>                                                    = 2(5) inches + 2(4) inches</em>

                                                   = 10 <em>inches</em>  + 4 <em>inches</em>

                                                   = 14 <em>inches</em> or 14 <em>in</em>

  Step-by-step explanation:

The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.

The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter<em> l</em> while the shorter side is known as width or breadth represented by letter <em>w</em> and<em> b </em>respectively. The perimeter is calculated by the formula 2(l + w). where l means the length and w represents the width.

Find the limits<br>The answer is - 3/4
Kipish [7]

Hello from MrBillDoesMath!

Answer:

This is a puzzling one! The answer is indeed -3/4 but I was unable to prove it using mathematics appropriate to the "middle school" level. Sorry I couldn't be more helpful.

(To prove it I generated the first few terms of its Laurent series, a Calculus topic. The first few terms are  -(3/4) + (41/64x) +  and as x approaches  minus infinity the term with "x" in the denominator goes to zero, leaving the constant value -3/4 as the answer. )


Thank you,

MrB

In remodeling a house an architect finds that by adding the same amount to each dimension of a 15ft by 19ft rectangular room, th
earnstyle [38]

Answer:

Step-by-step explanation:

new length=15+x

width=19+x

then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²

original area=15×19=285 ft²

then 285+98=x²+34x+285

or

x²+34x-98=0

x²+34x+17²=98+17²

(x+17)²=98+289=387

x+17=√387=3√43

x=3√43-17 ft
