Answer:

The width would be 9 + x

Step-by-step explanation:

In order to find this, we must first factor the area. This will give us two things that are being multiplied together.

81 - x^2 = (9 - x)(9 + x)

Since the area is the length times the width and the width is x - 9, we know the length must be x + 9

What is the area of a circle with a diameter of 18.2 cm?

Fudgin [204]

Answer:

260.0234 cm

Step-by-step explanation:

The formula for area of a circle is π r².

Since the radius is half of the diameter, we must divide the diameter by 2.

18.2/2 = 9.1

Next, we must multiply 9.1 x 9.1.

This gives us 82.81

Now we must multiply 82.81 by pi (3.14).

82.81 x 3.14 = 260.0234

Therefore, the area of the circle is 260.0234.

Avery weighs x pounds. Jada weighs 18 pounds more than Avery. Which expression tells how much the two of them weigh together? x

Rashid [163]

Answer:

Second option: $x + x + 18$

Step-by-step explanation:

You know that "x" represents the Avery's weigth (in pounds).

Let be "y" the weight of Jada in pounds.

Since Jada weighs 18 pounds more than Avery, you can write this expression:

$y=x+18$

The weight of them together is:

$weight\ together=x+y$

Substituting, you get:

$weight\ together=x+x+18$

Therefore, the expression that tells how much the two of them weigh together is the one provided in the second option:

$x + x + 18$
