-3x^2-16x- 5

Answer:

Answer:

x= 1/3 or x=4

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−13x+4=0

Step 1: Factor left side of equation.

(3x−1)(x−4)=0

Step 2: Set factors equal to 0.

Answer:

[tex]66.92\:\mathrm{m}[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex]l\cdot w[/tex] where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:

[tex]15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}[/tex].

The perimeter of a rectangle is given by [tex]p=2w+2l[/tex]. Therefore, the perimeter of the rectangle is:

[tex]2(15)+2(18.46)=\fbox{$66.92\:\mathrm{m}$}[/tex].

Answer:

Step-by-step explanation:

2y=10x-3( i arranged it to make it easier)

y=(10x-3) divided by 2

y=5x-1.5

they are parallel because they have the same gradient/slope number.

Answer:

A) 7 is the greatest common factor of the expression.

B) factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

Step-by-step explanation:

We are given the expression: [tex]14x + 28y + 21[/tex]

Part A: What is the greatest common factor of the expression?

We need to find the greatest common factor of the expression.

The expression is divisible by 7

So, 7 is the greatest common factor of the expression.

Part B: Factor the expression

We need to factor the expression: [tex]14x + 28y + 21[/tex]

Taking 7 common:

[tex]14x + 28y + 21\\=7(2x+4y+3)[/tex]

So, factoring the expression [tex]14x + 28y + 21[/tex] we get [tex]\mathbf{7(2x+4y+3)}[/tex]

Step-by-step explanation:

Answer:

+ 5°

Step-by-step explanation:

Given,

Good morning temperature = -15°

Raise in temperature = 20°

Afternoon temperature = -15° + 20°

           = + 5°

Hence, temperature in after noon is equal to + 5°.

Answer:

16xpi

Step-by-step explanation:

To find the area of a circle the formula is pi r squared.

r represents radius, aka 4x.

4 times 4 yields 16.

Leaving you with 16xpi

Answer:

50.24

Step-by-step explanation:

A= πr^2

3.14 x 4^2 = 50.24

(4^2=16)

Answer:

f(x) = 3(x - 2)² + 4

OR  

f(x) = 3x² - 12x + 16

Step-by-step explanation:

Vertex form of a parabola:

Standard form of a parabola:

Let's find the vertex of this parabola.

In order to find the a-value (vertex form), let's use another point besides the vertex on the parabola.

Using (3, 7) for (x, y), let's substitute this point and the vertex (2, 4) for (h, k) into the vertex form equation and solve for a.

Simplify using PEMDAS.

Subtract 4 from both sides.

Now we have (h, k) and a of the vertex form.

In order to convert from vertex to standard form, simplify the equation by FOILing.

Distribute 3 inside the parentheses.

Combine like terms.

Therefore, we have the answer:

Vertex form:

Standard form:

Answer:

I would assume you would use PEMDAS? thats what I would use

Answer:

Solve the parenthesis

Step-by-step explanation:

In the order of operations (PEMDAS), you would solve what's in the parenthesis first. So you would add 5 and 4, then multiply that by 3 to get the correct answer. Hope that helps!

Answer:

Choice 2

Step-by-step explanation:

Ask a friend or older sibling, they always have the answer (Not really)

Answer:

Answer:

x=3

Step-by-step explanation:

7−3x=−x+1

Step 1: Simplify both sides of the equation.

7−3x=−x+1

7+−3x=−x+1

−3x+7=−x+1

Step 2: Add x to both sides.

−3x+7+x=−x+1+x

−2x+7=1

Step 3: Subtract 7 from both sides.

−2x+7−7=1−7

−2x=−6

Step 4: Divide both sides by -2.

−2x

Step-by-step explanation:

Step 1: Define

[2 × (24 ÷ 3)] + 7

Step 2: Evaluate

Answer:

→ [2 × 24/3] + 7

Divide 24 by 3 we get 8 as the product:

→ [2 × 8] + 7

Now, multiply 8 by 2 we get product as 16 :

→ 16 + 7

Let's add the 16 and 7 and we get final answer as :

→ 23

Answer:

x is equal to seven.

Step-by-step explanation:

To solve this you can move like terms to each side, then divide both sides by the coefficient of x:

4 + 6x = -3 + 7x

6x -7x = -3 - 4

-x = -7

x = 7

Answer:

1/3

Step-by-step explanation:

When you divide 1 by 3, you get .3 repeating.

Answer:

n = 0.8

Step-by-step explanation:

3n + 3 = 5.4

-3 form each side

3n=2.4

÷3 for each side

n=0.8

Answer:

0.8

Step-by-step explanation:

3(n+1)=5.4

Divide both sides by 3

3(n+1)/3 = 5.4/3

simplify

n+1=1.8

subtract 1 from both sides

n+1-1=1.8-1

N=0.8

Answer:

  2. chord theorem; t = 10.5

  3. chord theorem; x = 5

Step-by-step explanation:

For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.

2. 20t = 10·21

  t = 210/20 . . . . divide by 20

  t = 10.5 . . . . . . . simplify

Step-by-step explanation:

Answer:

I think it is 14.1421356237. I needed you can round it down to 14.14.

Answer:

√1370 or about 37.01

Step-by-step explanation:

use distance formula

√(x2-x1)^2+(y2-y1)^2

sqrt(8-7)^2+(41-4)^2

sqrt(1)^2+(37)^2

sqrt 1+1369

sqrt 1370

= about 37. 01
