2x+4(7−x) HELP PLEASE IM DEPERATEEEEE

goldenfox [79]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{ - 2x + 28}}}}}$

Step-by-step explanation:

$\sf{2x + 4(7 - x)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{2x + 28 - 4x}}$

Collect like terms

$\dashrightarrow{ \sf{2x - 4x + 28}}$

$\dashrightarrow{ \sf{ - 2x + 28}}$

Hope I helped!

Best regards! :D

You have 42 ft. of fencing (1 ft. segments) to make a rectangular garden. How much should each side be to maximize your total ar

Verizon [17]

Answer:

$Length=10.5\ ft$

$Width=10.5\ ft$

$Area=110.25\ ft^{2}$

Step-by-step explanation:

Let

x----> the length of the rectangular garden

y---> the width of the rectangular garden

we know that

The perimeter of the rectangle is equal to

$P=2(x+y)$

we have

$P=42\ ft$

so

$42=2(x+y)$

simplify

$21=(x+y)$

$y=21-x$ ------> equation A

Remember that the area of rectangle is equal to

$A=xy$ ----> equation B

substitute equation A in equation B

$A=x(21-x)$

$A=21x-x^{2}$ ----> this is a vertical parabola open downward

The vertex is a maximum

The y-coordinate of the vertex is the maximum area

The x-coordinate of the vertex is the length side of the rectangle that maximize the area

using a graphing tool

The vertex is the point $(10.5,110.25)$

see the attached figure

so

$x=10.5\ ft$

Find the value of y

$y=21-10.5=10.5\ ft$

The garden is a square

the area is equal to

$A=(10.5)(10.5)=110.25\ ft^{2}$ ----> is equal to the y-coordinate of the vertex is correct
