Answer:

Step-by-step explanation:

A square surface is determined by the product of its sides

s = L ^ 2

Thus, the surface of the cardboard of side C, will be

x ^ 2 + 12x + 36 = C ^ 2

Factoring

(x + 6) (x + 6) = C ^ 2

THE SIDE IS (x + 6)

Answer:

$\boxed{(x+6)}$

Step-by-step explanation:

The surface of a square is $\sf side^2$ .

$s^2 =x^2 +12x+36$

Take the square root on both sides.

$s=\± \sqrt{x^2+12x+36}$

$s=\± (x+6)$

The side of the cardboard cannot be a negative value.

One sphere has a radius of 3 inches and another sphere has a radius of 6 inches. The volume of the larger sphere is about how ma

NikAS [45]

Answer:

Step-by-step explanation:

First off, we need to recognize that the formula for the volume of a sphere is $\frac{4}{3} \pi r^3$ .

Then, we can plug in our r values one at a time.

The volume for the sphere with a 6-inch radius is about 904.779.

The volume for the sphere with a 3-inch radius is about 113.097.

To find how much greater the larger sphere is, we simply create a ratio between the two numbers: $\frac{904.779}{113.097}$

Do the division to find that the volume of the larger sphere is about 8 times the volume of the smaller sphere.

The product of three whole numbers is 120 how many different possibilities are there for the three whole numbers

Sphinxa [80]

We can factor 120 into
2 * 2 * 2 * 3 * 5

I think there are nine different possibilities
1) 8 * 3 * 5
2) 4 * 2 * 15
3) 4 * 6 * 5
4) 4 * 10 * 3
5) 2 * 2 * 30
6) 2 * 3 * 20
7) 2 * 5 * 12
8) 2 * 6 * 10
9) 2 * 15 * 4

A boy, flying a kite, holds the string 5 feet above the ground and plays out string at 2 ft./sec. as the kite moves horizontally

yKpoI14uk [10]

Answer:x = 75

Step-by-step explanation:y=105 - 5 = 100 ft

z=125 ft

dz/dt=2 ft/sec

by using Pythagorean Theorem, we find x

x^2 + 100^2 = 125^2

x = 75
