TELEVISIONS in 1999, 68% of households with tv's subscribed to cable tv. if 8,000 more subscribers are added to the number of ho

Art [367]

Let x be the number of households with TV.

So .68x would be the number of households with cable.

If 8000 were added to the above number, it would be equal to 67,600,000.

Thus we have our equation:

.68x + 8000 = 67600000

Solving for x:

.68x = 67592000

x = 99,400,000

The length of a rectangle is 3 cm more than twice the width. The area of the rectangle is 65 square centimeters. Find the dimens

polet [3.4K]

Answer:

5 cm and 13 cm

Step-by-step explanation:

Let b be the width of the rectangle.

Length = 3+2b

The area of the rectangle is 65 cm²

We need to find the dimensions of the rectangle. The area of a rectangle is given by :

A = lb

$65=(3+2b)b\\\\65=3b+2b^2\\\\3b+2b^2-65=0\\\\b=5\ cm,-6.5\ cm$

Neglecting the negative value, the width of the rectangle is 5 cm.

Length = 3+2b

=3+2(5)

=3+10

=13 cm

Hence, the dimensions of the rectangle are 5 cm and 13 cm.
