The perimeter of a rectangle is 32 cm. The difference between the length and the width is 4cm. find the width

1 answer:

7 0

Length = x
width = y

2x + 2y = 32
x - y = 4
x = 4 + y

2(4+y) + 2y = 32
8 + 2y + 2y = 32
4y = 24
y = 6 cm (width)

x = 4 + 6
x = 10 cm (length)

ladessa [460]

Answer:

18/20π

Step-by-step explanation:

81π ÷ 1 = 81π

81π ÷2 = 18/20π

You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.

VikaD [51]

Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Step-by-step explanation:

Given expression is $(6x^2-4x+11)+(4-x^2-3x)$

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

$(6x^2-4x+11)+(4-x^2-3x)$

$=6x^2-4x+11+4-x^2-3x$

Adding the like terms we get

$=5x^2-7x+15$

$(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15$

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>
