The formula of a perimeter of a rectangle:

P = 2(l + w)

We have P = 34 and l = 2w - 4.

Substitute:

2(2w - 4 + w) = 34

2(3w - 4) = 34       <em>use distributive property</em>

(2)(3w) + (2)(-4) = 34

6w - 8 = 34       <em>add 8 to both sides</em>

6w = 42      <em>divide both sides by 6</em>

w = 7

l = 2w - 4 → l = 2(7) - 4 = 14 - 4 = 10

<h3>Answer: the length = 10 and the width = 7.</h3>

bekas [8.4K]

Answer:  D.gallons

Step-by-step explanation:

Kilogram is a unit of mass

Now, Pounds, Tons and Ounces are also units of mass.

But Gallons is a unit of volume, where 1 gal = 3.785 L

Then you never can represent an amount of mass using units for volume, which means that gallons is incommensurabe with kilograms.

The surface area of a sphere is 3000 m2. What is the volume of the sphere
riadik2000 [5.3K]

Answer:

The answer is

<h2>15448 cm³</h2>

Step-by-step explanation:

Volume of a sphere is

V =  \frac{4}{3} \pi {r}^{3}

where r is the radius

From the question in order to find the volume of the sphere we must first find the radius of the sphere using it's surface area

Surface area of sphere = 4πr²

3000 = 4πr²

Divide both sides by 4π

r² = 750/π

r = 15. 45 cm

Now the volume of the sphere is

V =  \frac{4}{3} \pi( {15 .45})^{3}

<h2>= 15448.06</h2>

<h3>= 15448 cm³ to the nearest whole number</h3>

Hope this helps you
