Answer:

4 pieces of chair rail are needed

Step-by-step explanation:

<u>Step 1: Calculate the perimeter of the room</u>

Perimeter of rectangle = 2L + 2B

Length = 18

Breadth = 14

Perimeter of room = 2(18) + 2(14)

Perimeter of room = 64 feet

<u>Step 2: Calculate the pieces of chair rail needed</u>

<em>Perimeter of room = 64 feet</em>

<em>Length of each chair rail = 16 feet</em>

<em>Total chair rails needed = Perimeter of room/length of each chair rail</em>

<em>Total chair rails needed = 64/16</em>

Total chair rails needed = 4

Therefore, Mr. Herzog needs 4 pieces of chair rails.

$y\cdot \:2\frac{1}{2} =$ $2\frac{1}{2}=\frac{2\cdot 2+1}{2}=\frac{5}{2}$ $=\frac{5y}{2}$

a) $2y+\frac{1}{2}=\frac{4y+1}{2}$

b) $2y+\frac{1}{2}y=\frac{5y}{2}$

Overline MD cong overline LS additional information is necessary to show that triangle MTD cong triangle LGS by SSS?

aivan3 [116]

Answer:

$TD \cong GS$

Step-by-step explanation:

See comment for complete question

Given:

$TM \cong GL$

$MD \cong LS$

Required

The information that shows $\triangle MTD \cong \triangle LGS$ by SSS

By SSS implies that, the three sides of both triangles are congruent

Already, we have:

$TM \cong GL$

$MD \cong LS$

The third side of $\triangle MTD$ is $TD$

The third side of $\triangle LGS$ is $GS$

So, for both to be congruent by SSS, the third sides must be congruent

i.e.

$TD \cong GS$

Help please help please

xxTIMURxx [149]

Answer:

Combine like terms

Step-by-step explanation:

The first step in such equations is to simplify the equation which is done most often by combining like terms, and by combining like terms i mean for example:

1 + 5 + 3x = 4y + z

You will combine the like terms (those that can be added or subtracted):

6 + 3x = 4y + z

In our example, combining terms would be adding 2x/3 and 1x/3 to give

3x/3 + 2 = 5

The equation is now simple and easy to solve as you simplify 3x/3 to 1x and then proceed to rearrange the equation to yield the value of x

Hope this helps!

What is 1/4(x+16)-x equal too

schepotkina [342]

<span>1/4(x + 16) - x =

First, distribute the 1/4.

= 1/4x + 1/4 * 16 - x

= 1/4x + 4 - x

= 1/4x + 4 - 4/4x

= 1/4x - 4/4x + 4

= -3/4x + 4

$= -\dfrac{3}{4}x + 4$ </span>
