Answer:

see explanation

Step-by-step explanation:

The width w is 4 feet longer than two times the length , then

w = 2l + 4

The area (A) of the rectangle is length × width , then

A = l(2l + 4) ← distribute parenthesis

A = 2l² + 4l

Given A = 16

2l² + 4l = 16

Subtract 16 from both sides

2l² + 4l - 16 = 0 ( divide through by 2 )

l² + 2l - 8 = 0 ← in standard form

(l + 4)(l - 2) = 0 ← in factored form

Equate each factor to zero and solve for l

l + 4 = 0 ⇒ l = - 4

l - 2 = 0 ⇒ l = 2

However l > 0 then l = 2

and w = 2l + 4 = 2(2) + 4 = 4 + 4 = 8

The length of the rectangle is 2 feet and

the width is 8 feet

Draw a line segment 7cm long .

White raven [17]

Answer:

The line segment 7 cm long is shown below.

Step-by-step explanation:

First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.

The length of each part is 1 cm.

Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.

From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

$7\times 1=7$

Hence the total length of line is 7 cm.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

$f\left(x\right)\:=x^3+2x^2-16x-32$

Let us determine the factors by solving

$\:\left0\right\:=x^3+2x^2-16x-32\:$

$\left(x+2\right)\left(x+4\right)\left(x-4\right)=0$

Using the zero factor principle:

if $ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0$

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

(x+2)

(x+4)

(x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

(x-2)
(x+6)
