Answer:

$\texttt{Area = Length x Width}\\\\\texttt{Area =}x\times (30-x)=30x-x^2\\\\\texttt{Area =}30x-x^2$

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>

Step-by-step explanation:

Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.

If the garden is X yards long, express the Gardens area as a function of length

Let x be the length of garden

So perimeter of rectangle = 60 yard

Perimeter = 2 * ( Length + width)

60 = 2 * ( x + width)

Width = 60/2 - x

Width= 30 - x

$\texttt{Area = Length x Width}\\\\\texttt{Area =}x\times (30-x)=30x-x^2\\\\\texttt{Area =}30x-x^2$

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>

connie poured 200 milliliters of juice into a glass from a juice carton. She then poured 225 milliliters into a second glass. Wh

Salsk061 [2.6K]

Answer:

A reduction of 450ml

Step-by-step explanation:

Given

$V_1 = 200ml$ -- To glass 1

$V_2 = 250ml$ --- To glass 2

Required

The final change to the carton

To do this, we simply add V1 and V2

So, we have:

$Total = V_1 + V_2$

$Total = 200ml + 250ml$

$Total = 450ml$

<em>This implies that the changes is a reduction of 450ml</em>

Two students, Carlos and Sophie, factored the trinomial -4x² − 10x + 6. Sophie factored it as -2(2x − 1)(x + 3) and Carlos facto

Grace [21]

Answer:

Sophie factored completely.

Carlos did not factor out a 2 out of his last term

Step-by-step explanation:

-4x² − 10x + 6

Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).

If you look at the last term in Carlos

(x + 3)( -4x + 2)

You can factor out a -2

(x+3) (-2)(2x-1)

It is not factored completely with the negative two inside the parentheses

He could also have factored out a 2

(x+3) (2)(-2x+1)

I like having a positive x so I use the -2

Either would be acceptable.
