Answer:

The width is: $w(x)=4x^2$

The length is $l(x)=2x^2+3x+5$

Step-by-step explanation:

The given rectangle has area given algebraically by the function:

$a(x)=8x^5+12x^3+20x^2$

The width of the rectangle is the greatest common factor of $8x^5$ , $12x^3$ and $20x^2$

That is the width is: $w(x)=4x^2$

We now divide the area by the width to obtain the length of the rectangle:

$l(x)=\frac{8x^5+12x^3+20x^2}{4x^2}$

This simplifies to:

$l(x)=\frac{8x^5}{4x^2}+\frac{12x^3}{4x^2}+\frac{20x^2}{4x^2}$

$l(x)=2x^2+3x+5$

Jen wants to have 8 rose bushes planted on her property. She asked a landscaping company to give her a bid. The contractor wante

Stella [2.4K]

Answer:

Jen saved $320.

Step-by-step explanation:

Since she would like 8 bushes total and 1 = $60, we will multiply (60 x 8) to get a total of $480.

Finally, to find out how much Jen saved, we must subtract Jens final priced total ($480) - the landscapers asking price ($800) to get ( = $320)

Jen payed $480 and saved $320.

Hope this helps...

The figure shown is made up of triangle ABF and rectangle BCDE. The area of the figure is 90 square feet. If AB=BC=BF=FE, find A

Ludmilka [50]

The complete question in the attached figure

let
x-----> distance AB
so
AC=2x

we know that
area of the figure=area of triangle+area of rectangle
area of the figure=90 ft²

step 1
find the area of triangle
$A=b*h/2$
b=x
h=x
so
$A=(x*x)/2$
Area of triangle=x²/2 ft²

step 2
find the area of rectangle
$A=b*h$
b=2x
h=x
$A=(2x)*x------\ \textgreater \ A=2x^{2}$
area rectangle=2x²

step 3
find value of x
area of the figure=(x²/2)+2x²
area of the figure=90 ft²
90=(x²/2)+2x²-----> multiply by 2 both sides----> 180=x²+4x²
5x²=180-----> x²=36-----> x=6 ft

AC=2x-----> AC=2*6----> AC=12 ft

the answer is
AC=12 ft

Write a function in vertex form that is translated 3 units down and 3 units to the right of f (x) = x^2

alexandr1967 [171]

Answer:

f(x)= (x-3)^2-3

Step-by-step explanation:

Vertex Form: y= a(x-h)^2+k

a is the reflection

h and k are the vertex so in an ordered pair (x,y) = (h,k)

Since it is translating 3 units down it is going to be a negative 3. If it was translating up it would be positive 3. This represents the "k" because it is moving on the y-axis.

Since it is translating 3 units to the right it is going to be positive 3. If it was translating left it would be negative 3. This represents the "h" because it is moving on the x-axis.

After plugging it into the vertex form formula: f(x)= (x-3)^2-3

*notice when I plugged the "h" in it became negative because x-(3)= x-3*
