Answer:

Area = (a² -5a) in²

Perimeter = (4a -10) in

Step-by-step explanation:

Let the length of the rectangle be a.

Given that, its width is 5 in less than the length.

So,

length ⇒ a

width ⇒ (a - 5)

First, let's find the area of the rectangle.

Area = length × width

Area = a ( a - 5 )

<em>Solve the brackets.</em>

Area = <u>(a² -5a) in²</u>

<u />

Now, let us find the perimeter of the rectangle.

Perimeter = 2 ( l + w )

Perimeter = 2 ( a + a - 5 )

Perimeter = 2 ( 2a - 5 )

Perimeter = <u>(4a -10) in</u>

QveST [7]

The correct answer is 3380 meters

Explanation:

The initial elevation of the hike can be represented as -20 meters, this is because the initial elevation is below the sea level, and in terms of elevation the sea level is considered to be 0. Now, using this number the final elevation can be calculated by adding the two numbers:

-20 + 3400 = 3380

This implies the final elevation has 3380 meters

You can also get this same result by considering there are 20 meters from the initial elevation to the sea level and then 3380 meters from the sea level to the final elevation (3380+20 = 3400).

CAN SOMEONE PLEASE EXPLAIN THIS FOR ME PLEASE HELP
Nata [24]

The equation that describes the given polynomial is:

P(x) = x²*(x - 2)²*(x + 2)

<h3>How to find the equation for the polynomial?</h3>

Remember that a polynomial with a leading coefficient A and roots:

x₁, x₂, x₃,...,xₙ

The equation that describes the polynomial is:

P(x) = a*(x - x₁)*(x - x₂)*...*(x - xₙ)

In this case, we know that the leading coefficient is 1, and the roots are:

2, 2, 0, 0, -2.

(the first two appear two times because have a multiplicity of two).

Then we can write the equation of the polynomial as:

P(x) = 1*(x - 2)*(x - 2)*(x - 0)*(x - 0)*(x + 2)

P(x) = x²*(x - 2)²*(x + 2)
