The length of a rectangle is 2 feet less
than three times the width. If the
perimeter is 68 feet, what are the
dimensions of the rectangle?

Answer:

Option C. is the correct answer

Step-by-step explanation:

Choose any value of x and find the values of y. Then plot a graph using all that points. These will neither parallel nor perpendicular.

Answer:

A

Step-by-step explanation:

2 and 4 are on opposite sides of the transversal but both on the inside of the parallel lines. This makes them alternate interior angles, which are congruent.

Answer:

He gave you 48 cards.

Step-by-step explanation:

150 * 32% (which is also 0.32) is equal to 48.

Divide the percentage by 100.

32 / 100 = 0.32.

You then multiply 0.32 by 150 to get the part.

0.32 x 150 = 48.

32% of 150 is 48.

Your answer is 48 cards.

Answer:

the answer is ( p+2 ) (p+16)

We can use the pythagorean theorem to solve this

The pythagorean theorem = a^2 + b^2 = c^2, while

a = one leg

b = the second leg

c = the hypotenuse

In this problem,

a = 3

b = 15

c = ?

Let's plug our values into the pythagorean theorem

(3)^2 + (15)^2 = c^2

9 + 225 = c^2

Add together the left side

234 = c^2

Take the sqrt of both sides

sqrt(234) = c

The length of BC = sqrt(234)

Answer:

[tex] \boxed{ \sf{length \: of \: a \: rectangle = 60 \: yd}}[/tex]

[tex] \boxed{ \sf{width \: of \: a \: rectangle = 10 \: yd}}[/tex]

Step-by-step explanation:

Let the width of a rectangle be 'w'

Length of a rectangle ( l ) = 6w

Perimeter of a rectangle ( P ) = 140 yd

Finding the width of a rectangle

[tex] \boxed{ \sf{perimeter \: of \: rectangle= 2(length + breadth)}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 2(6w + w)}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 2 \times 7w}}[/tex]

[tex] \dashrightarrow{ \sf{140 = 14w}}[/tex]

[tex] \dashrightarrow{ \sf{14w = 140}}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{14w}{14} = \frac{140}{14}}} [/tex]

[tex] \dashrightarrow{ \sf{w = 10}}[/tex]

Width of a rectangle = 10 yd

Now, replacing / substituting the value of w in 6w in order to find the length of a rectangle

[tex] \dashrightarrow{ \sf{length = 6 \times x = 6 \times 10 = 60 \: yd}}[/tex]

Length of a rectangle = 60 yd

Hope I helped!

Answer:

Step-by-step explanation:

5x - 6y = 27 .......... Equation 1

7x + 6y = 9 ………… Equation 2

To solve using elimination add the second equation to the first one to eliminate y

That's

5x - 6y + 7x + 6y = 27 + 9

12x + 6y - 6y = 36

12x = 36

Divide both sides by 12

x = 3

Substitute it into any of the equations

Using equation 2

That's

7(3) + 6y = 9

21 + 6y = 9

6y = - 12

Divide both sides by 6

y = - 2

The solutions are

x = 3

y = - 2

Answer:

-124

Step-by-step explanation:

The equation for a discriminant is:

[tex]b^{2} -4ac[/tex]

So for

[tex]7x^{2} -4x +5=0[/tex]

a = 7         b = - 4          c = 5

Plug values into the equation.

[tex](-4)^{2} -4(7)(5)[/tex]

16 - 140 = -124

Answer:-124

Step-by-step explanation:

b^2 - 4ac

a = 7  b = -4   c = 5

-4^2 - 4*7*5

16 - 4*35

16 - 140

-124

Answer:

14 books

Step-by-step explanation:

Let b = number of books at the beginning

She sold 1/2 of the books

b - 1/2 b

This is how many she had left

Then she bought 7

b - 1/2 b + 7

this equals 14

b - 1/2 b + 7 = 14

Combine like terms

1/2 b + 7 = 14

Subtract 7 from each side

1/2 b = 14-7

1/2 b = 7

Multiply each side by 2

1/2 b * 2 = 7*2

b = 14

She started with 14 books

Answer:

A. x-4y=8

Step-by-step explanation:

Slope = [tex]\frac{1}{4}[/tex]

y-intercept = -2

In y=mx+b

m = slope

b = y-intercept

Just replace m with 1/4 and b  with -2

[tex]y = \frac{1}{4} x -2\\[/tex]

Multiply through by 4 and re-arrange

[tex]4(y=\frac{1}{4} x -2)\\\\4y =x -8\\0 =-4y +x-8\\8 =-4y+x\\\\x -4y =8[/tex]

[tex]\huge\boxed{A=(9x^2-48x+64)ft^2}[/tex]

Step-by-step explanation:

The formula of an area of a square:

[tex]A=s^2[/tex]

[tex]s[/tex] - side of a square

We have [tex]s=(3x-8)ft[/tex]

Substitute:

[tex]A=(3x-8)^2[/tex]

METHOD 1:

Use  [tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]A=(3x)^2-2(3x)(8)+8^2=9x^2-48x+64[/tex]

METHOD 2:

Use FOIL: [tex](a+b)(c+d)=ac+ad+bc+bd[/tex]

[tex]A=(3x-8)(3x-8)=(3x)(3x)+(3x)(-8)+(-8)(3x)+(-8)(-8)\\\\=9x^2-24x-24x+64=9x^2-48x+64[/tex]

Answer:

9x^2-48x+64 ft^2

Step-by-step explanation:

(3x − 8) (3x − 8)

Multiply 3x by (3x − 8)

3x(3x − 8)

9x^2-24x

Multiply - 8 by (3x − 8)

- 8(3x − 8)=-24x+64

Combine 9x^2-24x and -24x+64

9x^2-48x+64 ft^2

We see that 4 and 7 add to make 11, but not -11. Well, we can just make both of them negative and then it will be -11 and their product will still be 28. Our numbers are -4 and -7.
