Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2+1 inches. She plans to make a similar pillow, including the ribbon, whose side length is 4x−7 inches. What expression can be used for the length of ribbon that she needs for both pillows, and what is the length if x = 3.5?

2x2+4x−6; 22.0 inches
2x2+4x−6; 32.5 inches
4(2x2+4x−6;) 88.0 inches
4(2x2+4x−6;) 130.0 inches

Answer:

We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]

Both have same slope, so EF is parallel to GH i.e. EF || GH

Step-by-step explanation:

We need to find Is EF and GH parallel.

If EF and GH are parallel, they have same slopes.

So, we will find slopes of EF and GH

The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of EF

We have: E(2,5) and F(7,1)

So, [tex]x_1=2, y_1=5, x_2=7, y_2=1[/tex]

Putting values in formula and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-5}{7-2}\\Slope=\frac{-4}{5}\\[/tex]

So, slope of EF is [tex]\mathbf{\frac{-4}{5}}[/tex]

Slope of GH

We have: G(2,-3) and F(-3,5)

So, [tex]x_1=2, y_1=-3, x_2=-3, y_2=5[/tex]

Putting values in formula and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{-8-2}\\Slope=\frac{5+3}{-10}\\Slope=\frac{8}{-10}\\Slope=\frac{-4}{5}[/tex]

So, slope of GH is [tex]\mathbf{\frac{-4}{5}}[/tex]

We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]

Both have same slope, so EF is parallel to GH i.e. EF || GH

Answer: y=  2/3 + -8

Step-by-step explanation: Put into slope intercept form

The  equation of the line with a slope of 2/3  and y -intercept of -8 is y = 2/3 x -

8

The slope intercept equation is represented as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

The equation of the line has a slope(m) of 2 / 3 and y-intercept of  -8.

The equation can be represented as follows:

y = 2/3 x - 8

Answer: 4 cards are left to be colored.

Step-by-step explanation:

As per given,

Fraction of total cards colored = [tex]\dfrac12+\dfrac38[/tex]

[tex]=\dfrac{4+3}{8}\\\\=\dfrac{7}{8}[/tex]

Fraction of cards left to be colored = [tex]1-\dfrac78=\dfrac18[/tex]

Total cards = 32

Number of cards to be colored = [tex]\dfrac18\times32=4[/tex]

Hence, 4 cards are left to be colored.

Step-by-step explanation:

As is often the case with multiple choice questions, you only need to identify a feature of the answer set that distinguishes right from wrong. Here, that can be the lowest-power term, which is always the product of the lowest-power terms.

That product is (-3m)(+m) = -3m². This matches the third answer choice.

Answer:

x = 2

Step-by-step explanation:

Given

- 2(1 - 4x) = 3x + 8 ← distribute left side

- 2 + 8x = 3x + 8 ( subtract 3x from both sides )

- 2 + 5x = 8 ( add 2 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2
