The area, which is L x W.
L = x+14
W = x-20
Therefore, LW or (x+14)(x-20) is the area

Answer: The area

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>Length: x+14 </em>
<em>Width: x-20 </em>

So, if we multiply both measures we will obtain the area of the school gym.

Because:

Area of a rectangle = Length x width

Replacing with the values given

A = (x+14) (x-20)

In conclusion, (x+14) (x-20) represents the Area of the gym.

Metal A has a density of 12.7 g/cm3.

stira [4]

Using the given information, the density of metal B is 8.58 g/cm³

<h3>Calculating density </h3>

From the question, we are to determine the density of metal B

From the given information,

55 g of metal A is combined with metal B to create an alloy with mass 90 g

∴ Mass of metal B in the alloy = 90 g - 55 g = 35 g

Now, we will determine the volume of metal A in the alloy

Using the formula,

Density = Mass / Volume

∴ Volume = Mass / Density

Volume of metal A in the alloy = 55/12.7

Volume of metal A in the alloy = 4.33 cm³

Then, we will determine the volume of the alloy

Volume of the alloy = 90/10.7

Volume of the alloy = 8.41 cm³

∴ Volume of metal B in the alloy = 8.41 cm³- 4.33 cm³

Volume of metal B in the alloy = 4.08 cm³

Now, for the density of metal B

Density = mass / volume

Density of metal B = 35 / 4.08

Density of metal B = 8.58 g/cm³

Hence, the density of metal B is 8.58 g/cm³.

Solve for x <br>x/3 = 5/8

dlinn [17]

Answer:

x = 15/8

Step-by-step explanation:

x/3 = 5/8

Using cross products

8x = 3*5

8x = 15

Divide each side by 8

8x/8 = 15/8

x = 15/8

Answer:

g(x)=3(x+3)^2-8

Step-by-step explanation:

You can solve by using these acronyms.

H. orozontal.

I. nside.

O. pposite.

Meaning that a horozontal translation would be written inside the parenthesis and the poopsite sigh you would usually (Ex. Left is usually negitave but in this case it is positive).

The other acronym is,

V. erticle.

O. utside.

S. ame.

Meaning for a vrerticle translation the number would go on the outside of the parenthesis and tha sign would be normal (Ex. Negitave would be left and positive would be right).

For this one use H.I.O sinse you are moving on a horozontal plain. You are only working with the (x-2) nothing else matters.

Since you are moving left the number will move up 3 hence the O.

<h2><u>This transformation leaves you with g(x)=3(x+3)^2-8</u></h2>
