Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 5 x + 6 = 0

The left hand side factors into a product with two terms:

(x + 2) (x + 3) = 0

Split into two equations:

x + 2 = 0 or x + 3 = 0

Subtract 2 from both sides:

x = -2 or x + 3 = 0

Subtract 3 from both sides:

Answer: |

| x = -2 or x = -3

Answer:

0.783, just look at the pattern.

If you're comparing, this is the answer:

<

Answer:

x = 12 radical 2 ithink these is ansewer

Answer:

I'm guessing the opposites are negative and positive so whenever you add two opposite numbers it will always be 0. The answer will always be 0.

For example:

-3 + 3 = 0

4 - 4 = 0

-15 + 15

Answer:

0

Step-by-step explanation:

there is no 6 option on the spinner

Answer:

3x + 2y = 11

3x + y = 11 - 2

3x + y = 9

x + y = 9/3

x + y = 3

x = 3 - y

5x - y = 14

x - y = 14/5

x - y = 2.8

x = 2.8 + y

14Answer:

3

Step-by-step explanation:

solve for y in first equation

5x-y=14

-y=14-5x

y=5x-14

substitute y value (5x-14) into 2nd equation

3x+2 (5x-14)=11

3x+10x-28=11

13x=39

x=3

Answer:

the interest is $9,676.91 and the future value amount is $19,876.91

Step-by-step explanation:

The computation is shown below;

The future value is

= Present value × (1 + rate of interest)^number of years

= $10,200 × (1 + 0.21)^3.5

=  $19,876.91

Now the interest amount is

= Future value - present value

= $19,876.91 - $10,200

= $9,676.91

Hence, the interest is $9,676.91 and the future value amount is $19,876.91

Answer:

Although a cylinder is technically not a prism, it shares many of the properties of a prism. Like prisms, the volume is found by multiplying the area of one end of the cylinder (base) by its height.

Answer:

  5.1 cm²

Step-by-step explanation:

The area of a segment is given by the formula ...

  A = 1/2r²(α -sin(α)) . . . . . where α is the central angle in radians

For this segment, its area is ...

  A = 1/2(6 cm)²(7π/18 -sin(70°)) ≈ 5.077 cm²

The area of the segment is about 5.1 square centimeters.

_____

The angle is converted to radians by multiplying by π/180°. Then a 70° angle is π(70°/180°) = 7π/18 radians.

Answer:

e and c

Answer:

Step-by-step explanation:

Area of the top section:

Area of the bottom section:

Total area:

Correct choices are C and D

Answer:

C & D

Step-by-step explanation:

top box area = x(x-(x-3)) = 3x

bottom box area = (x+4)(x-3) = x^2 -x -12

so correct ans is C & D

Answer:

[tex]\sqrt{9x^2+36} = 6 \csc(\theta)[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{2}=\cot(\theta)[/tex]

Required

Express [tex]\sqrt{9x^2+36}[/tex] as trigonometry expression

[tex]\sqrt{9x^2+36}[/tex]

Factorize

[tex]\sqrt{9x^2+36} = \sqrt{9(x^2+4)}[/tex]

Split

[tex]\sqrt{9x^2+36} = \sqrt{9} * \sqrt{(x^2+4)}[/tex]

[tex]\sqrt{9x^2+36} = 3 * \sqrt{(x^2+4)}[/tex]

[tex]\sqrt{9x^2+36} = 3\sqrt{(x^2+4)}[/tex]

We have:

[tex]\frac{x}{2}=\cot(\theta)[/tex]

Make x the subject

[tex]x = 2 \cot(\theta)[/tex]

So:

[tex]\sqrt{9x^2+36} = 3\sqrt{(x^2+4)}[/tex]

[tex]\sqrt{9x^2+36} = 3\sqrt{((2 \cot(\theta))^2+4)}[/tex]

Evaluate all squares

[tex]\sqrt{9x^2+36} = 3\sqrt{4\cot^2(\theta)+4}[/tex]

Factorize

[tex]\sqrt{9x^2+36} = 3\sqrt{4(\cot^2(\theta)+1)}[/tex]

Split

[tex]\sqrt{9x^2+36} = 3\sqrt{4} * \sqrt{\cot^2(\theta)+1}[/tex]

[tex]\sqrt{9x^2+36} = 3*2 * \sqrt{\cot^2(\theta)+1}[/tex]

[tex]\sqrt{9x^2+36} = 6 * \sqrt{\cot^2(\theta)+1}[/tex]

In trigonometry

[tex]\cot^2(\theta)+1 = \csc^2(\theta)[/tex]

So, we have:

[tex]\sqrt{9x^2+36} = 6 * \sqrt{\csc^2(\theta)}[/tex]

Evaluate the square root

[tex]\sqrt{9x^2+36} = 6 * \csc(\theta)[/tex]

[tex]\sqrt{9x^2+36} = 6 \csc(\theta)[/tex]
