Answer: OPTION B

Step-by-step explanation:

The formula for calculate the area of a rectangle is the shown below:

A=L*w

Where the lenght is l and the width is w

You know that the width is 6 feet less than it's length. Therefore, you must substitute w=l-6 into the formula show above.

Therefore, the quadratic function that expresses the rectangles area in terms of its length is:

A(L)=L(L-6)

A(L)=L^2-6L

Answer:

B. A( L) = L² - 6L

Step-by-step explanation:

A rectangle has 2 sides, length and width.

length = L

width = L - 6

Area = length × width

        = L(L - 6)

        = L² - 6L

The correct choice is B.

B. A( L) = L² - 6L

How do you solve: f(x) = -x2e-x<br> +2xe-x , finding the zero's of f.
Maksim231197 [3]

Answer:

0 and 2

Step-by-step explanation:

f(x) = -x^2e^{-x}+2xe^{-x}

To find zeros set f(x)=0  and solve for x

0 = -x^2e^{-x}+2xe^{-x}

0 = -e^{-x}(x^2-2x)

now factor out x

0 = -xe^{-x}(x-2)

set each factor =0 and solve for x

x=0

-e^{-x}=0 no solution for x

x-2=0, x=2

zeros of f  are 0 and 2
