the length of a rectangle is equal to triple the width . if the perimeter is 8 centimeters .what is the length and the width of
madam [21]

Answer:

Length = 3 cm

Width = 1 cm

Step-by-step explanation:

Let the length of rectangle be l and width of rectangle be w.

According to problem,

l = 3w  {Length of rectangle is equal to triple the width}

And Perimeter,P = 8 cm

Since, P = 2 ( l + w )

or 8 = 2( l + w)

Plug l =3w in the above perimeter equation.

We get:

8 = 2( 3w + w)

8 = 2(4w)

8 = 8w

or    w = 1 cm

Then length ,l = 3w =3 * 1 = 3 cm

Hence length of rectangle is 3cm and width of rectangle is 1cm.

Which equation is represented by the table?
MatroZZZ [7]

Answer:

y=-|x-3|-3

Step-by-step explanation:

The table shows values of y for different values of x.

Let us test each equation with the values given in the table.

Equation 1: y=|x+3|-3

For x = 1, we get,

y=|x+3|-3=|1+3|-3=|4|-3=4-3=1

So, we got 1 for y. But as per table, value of y should be -5.

So, equation 1 is incorrect.

Equation 2: y=-|x-3|-3

For x = 1, we get,

y=-|x-3|-3=-|1-3|-3=-|-2|-3=-(2)-3=-5

So, we got -5 for y. It matches with the value of table.

Let us check for another value of x in order to confirm.

For x =2, we get,

y=-|x-3|-3=-|2-3|-3=-|-1|-3=-(1)-3=-4

So, we got -4 for y. It matches with the value of table.

So, equation 2 is the correct answer.

We can be completely sure by checking the remaining equations too.

Equation 3: y=|x-3|-3

For x = 1, we get,

y=|x-3|-3=|1-3|-3=|-2|-3=2-3=-1

So, we got -1 for y. But as per table, value of y should be -5.

So, equation 3 is incorrect.

Equation 4: y=-|x+3|-3

For x = 1, we get,

y=-|x+3|-3=-|1+3|-3=-|4|-3=-4-3=-7

So, we got -7 for y. But as per table, value of y should be -5.

So, equation 4 is incorrect.
