pls help finding X
thank you if u do (Pls do not spam i have this in my test so need to learn)

Since you're trying to find f(-3), your function that you have to plug -3 into will be f(x).

f(-3) = -2(-3)^2+(-3)+3

f(-3) = -2(9)+(-3)+3

f(-3) = -18-3+3

f(-3) = -18 is your final answer

Answer:

45

Step-by-step explanation:

9:9,18,27,36,45

15:15,30,45

Answer:

45

Step-by-step explanation:

The least common multiple is the smallest number found between the two numbers, in this case 9 and 15, while skip counting from each number. Or the like the multiplication table.

Multiples for 9:

9, 18, 27, 36, 45, 54, 63...

Multiples for 15:

15, 30, 45, 60, 85...

45 is the first and common number that appears in both multiples of 9 and multiples of 15. Therefore, it will be the least common multiple of 9 and 15.

Answer:

$1.75

Step-by-step explanation:

basically we are comparing

5 daily passes vs. a weekly pass.

5 daily passes = 5×$5.35 = $26.75

a weekly pass = $25.00

so, the difference is 26.75 - 25 = $1.75

because 146 - 144 = 2

and nothing in the answer options shows anything like it.

now, if the problem actually said for example

14×6 - 14×4

that could be expressed as

14×(6-4) = 14×2

and that could be the first answer option (also with missing multiplication symbol).

Answer:

x is the base in (x^2 + 3)

Step-by-step explanation:

The base is x because it is being raised to a square or to the 2nd power  in (x^2 + 3). The base of an expression or exponent is always the number that is being raised to a power.  

In the expression (x2 + 3), the base is x.

Answer:

50.24 cm^2.

Step-by-step explanation:

If d = 8 then r = 4 cm.

Area = 3.14 * r^2

= 3.14 * 4^2

= 50.24 cm^2.

Answer:

We can cancel out A and B because there is no distributive property, and then I would say its C or the 3rd one.

Step-by-step explanation:

I used the cancelling out method.

Answer:

12.75

Step-by-step explanation:

Given the equations

x - y = 3.5 → (1)

[tex]\frac{x+y}{2}[/tex] = 11 ( multiply both sides by 2 to clear the fraction )

x + y = 22 → (2)

Add (1) and (2) term by term to eliminate y

2x + 0 = 25.5

2x = 25.5 ( divide both sides by 2 )

x = 12.75

Substitute x = 12.75 into (2)

12.75 + y = 22 ( subtract 12.75 from both sides )

y = 9.25

The 2 numbers are 12.75 and 9,25

With the larger number being 12.75

Hey there! I'm happy to help!

This glass is most likely a cylinder. To find the volume of a cylinder you take the area of the circle base and multiply it by the height.

To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14 for pi).

Our radius is 3cm.

3

We square it.

3²=9

Multiply by 3.14.

9×3.14=28.26

Now that we have our circle base area, we multiply it by the height (7 cm).

28.26×7= 197.82

This is how many cubic centimeters the glass can hold if it is completely full. However, we want half full, so we can just divide by 2.

197.82/2=98.91

We can also multiply our circle base by 3.5, which will give us half of the full height.

So, the height of the water is 3.5 cm and the volume of the water is 98.1 cm³.

Have a wonderful day and keep on learning! :D

Answer:

A.) w² + 3w in²

B.) 28 in²

Step-by-step explanation:

A.)

Let w = width and l = length.

    The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.

A(rectangle) = lw = (w + 3) · w = w² + 3w

B.)

Use the polynomial we previously found to find the area.

A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²

Answer:

c.15+2z/6x-12y

f.7a+b/4a-6b

Step-by-step explanation:

z+1/x-2y - 2x-3/2x-4y + z/3x-6y

z+1/x-2y - 2x-3/2(x-2y) + z/3(x-2y)

6(z+1)-3(2z-3)+2z

15+2z/6x-12y

3a/2a-3b - a+b/2(-3b+2a)

6a+a+b/2(2a-3b)

7a+b/4a-6b

Answer:

2

Step-by-step explanation:

√20 ÷ √5

√20/√5

=> √(20/5)

=> √4

=> 2

Let the width, w = x m

So, according to the Question,

The length, l = 3x m

Perimeter of a rectangle = 2 (l + w) m

Perimeter of the rectangle = 96 m

It's equation will be,

2 (3x + x) m = 96 m

or, 4x m = 96/2 m

or, 4x m = 48 m

or, x m = 48/4 m

or, x m = 12 m

Therefore, the width and the length of the rectangle is 12 m and 3(12) m = 36 m respectively.

Answer:

5d² - 3d

Step-by-step explanation:

Given

4d² + d² - 2d - d ← collect like terms

= (4 + 1)d² + (- 2 - 1)d

= 5d² + (- 3)d

= 5d² - 3d

Answer:

49.92 cm²

Step-by-step explanation:

Area of a triangle = base × height ÷ 2

7.8 × 12.8 ÷ 2 = 49.92

The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).

$3.56    $3.29     $3.26

  |------------|------------|

To order the prices from greatest to least, we'll compare the amounts spent on each day:

1. Wednesday: $3.56

2. Thursday: $3.29

3. Tuesday: $3.26

So, in order from greatest to least, the prices are:

$3.56 > $3.29 > $3.26

Now, let's represent this order on a number line:

 $3.56        $3.29        $3.26

  |------------|------------|

The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).

Answer:

Step-by-step explanation:

[tex] \frac{(5m - 4)}{6} - 1 = 4m - \frac{(3m + 10)}{2} [/tex]

[tex] = > \frac{5m - 4 - 6}{6} = \frac{8m - 3m - 10}{2} [/tex]

[tex] = > \frac{5m - 10}{6} = \frac{5m - 10}{2} [/tex]

[Cross Multiplication]

=> 2(5m - 10) = 6(5m - 10)

=> 10m - 20 = 30m - 60
