The length of a rectangle is 5 inches more than its width, x. The area of a rectangle can be represented by the equation x2 + 5x
nikdorinn [45]

Answer:

  width: 15 inches; length: 20 inches

Step-by-step explanation:

The equation tells you the product of width (x) and length (x+5) is 300, so you're looking for factors of 300 that differ by 5.

  300 = 1·300 = 2·150 = 3·100 = 4·75 = 5·60 = 6·50 = 10·30 = 12·25 = 15·20

The factors in the last pair on this list differ by 5, so we have ...

  • width = 15 inches
  • length = 20 inches

PLEASE HELP
Andrei [34K]

Given that the radius of the circle is 6 cm.

The central angle is 120°

We need to determine the length of AB.

<u>Length of AB:</u>

The length of AB can be determined using the formula,

{arc \ length}=2 \pi r\left(\frac{\theta}{360}\right)

Substituting \theta=120 and r=6 in the above formula, we get;

arc\ length}=2 \pi (6)\left(\frac{120}{360}\right)

Simplifying the values, we get;

arc\ length}=2 \pi (6)\left(\frac{1}{3}\right)

arc\ length}=12 \pi \left(\frac{1}{3}\right)

arc\ length}=4 \pi

Substituting π = 3.14, we have;

arc\ length}=4(3.14)

arc\ length}=12.56

Thus, the arc length of AB is 12.56 cm
