3x– 2.

What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

given that,

the expression is : 3x– 2

now, we have to find the expression which is not equivalent to 3x– 2.

now, we have, from the given options:

1.) x+x-1-1+x

= 3x - 2 , which is equivalent to 3x– 2.

2.) 2x+ 2+x

= 3x + 2 , which is not equivalent to 3x– 2.

3.) 3-x+ 2x-5 + 2x

= 3x - 2, which is equivalent to 3x– 2.

4.) 4x- 4-x+2

= 3x - 2, which is equivalent to 3x– 2.

Hence, The solution is, 2x+ 2+x, is the expression which is not equivalent to 3x– 2.

Answer:

VA

Step-by-step explanation:

Angle VYA = 180-94-46 = 40 degrees.

Know that the side length opposite the smallest angle has the smallest length.

VY and VA are the two smallest, but 40 < 46, therefore VA is the shortest length.

Short (and not very rigorous) proof:

The law of sines says that sinA/a = sinB/b = sinC/c, where x is the side opposite the angle X

sin46/YV = sin40/VA

sin46 > sin40, therefore YV > VA.

A group of friends wants to go to the amusement park. They have $94.25 to spend on parking and admission. Parking is $14.75, and tickets cost $13.25 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.

Answers

Answer: 6

Step-by-step explanation:

From the question, we are informed that a group of friends wants to go to the amusement park and that they have $94.25 to spend on parking and admission.

We are further told that Parking is $14.75, and tickets cost $13.25 per person, including tax. The equation that can be used to solve the number of people who can go to the amusement park would be:

= 14.75 + 13.25p

Since they've $94.25 to spend, the number of people that can go to the amusement park will be:

14.75 + 13.25p = 94.25

13.25p = 94.25 - 14.75

13.25p = 79.50

p = 79.50 / 13.25

p = 6

6 people can go to the amusement park

[tex]\frac{4}{3x-4}[/tex]

Step-by-step explanation:

The first thing we do to solve this is factor is completley

You can factor out a 4 from the numerator and get

4(3x+4)

The denominator is a  difference of squares which means that

(x^2-y^2)=(x-y)(x+y)

which means that 9x^2-16=

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

Put these together and get

[tex]\frac{4(3x+4)}{(3x-4)*(3x+4)}[/tex]

The 3x+4 cancels out and we get left with

Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a sting of light around. what length of lights should he buy?

Answers

Answer:

78 feet

Step-by-step explanation:

assuming it's the perimeter

25 + 25 + 14 + 14 = 78

The length of the string of the lights is 78 feet.

What is the perimeter of the rectangle?

P = 2(l + w), where 'l' is the length of the rectangle and  w is the width of the rectangle

For given example,

Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a string of light around.

The length of the string of the lights = the perimeter of the rectangular wooden deck

Here, length of the deck (l) = 25 ft.

width of the deck (w) = 14 ft.

Using the formula of the perimeter of the rectangle,

⇒ P = 2 × (l + w)

⇒ P = 2 × (25 + 14)

⇒ P = 2 × 39

⇒ P = 78 ft.

The perimeter of the rectangular wooden deck is 78 feet.

Therefore, the length of the string of the lights is 78 feet.

The equation would be y = 3x

Explanation:
The slope intercept form is y =mx +b

You start at the middle point and count up 3 until you’re on the same line as the other point and then you count over 1. That is your slope, your mx. Which is 3x (because the 1 doesn’t need to be shown) and the b is 0 meaning the point that is on the Y line. You start at 0 so you don’t need to put that in.

The answer is C. The slope formula, y2-y1 over x2-x1, which can be remembered as rise over run, can be used to solve. The y2 is 7 as it is the second y and then 1, the first y, is subtracted from it. 7-1=6. After this, you find the second x which is 3, and subtract -6 from it, meaning that you add it as you are subtracting a negative and they cancel out. You now have 3-(-6), or 3+6 on the bottom and 7-1 on the top. 7-1=6 and 3+6=9. The answer is the 6/9 and can be simplified down to 2/3 because of their shared greatest common factor, 3. Hope this helps.
