Answer:

x ≈ - 5.32, x ≈ 1.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2) x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Then

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

Answer:

volume =183.26 cm³

Step-by-step explanation:

volume of a cone = 1/3πrl

l is the slant height

using; l²=h²+r²

r²= l²-h²

r²= 25²-24²= 625-576 =49

r=√49=7cm

volume = 1/3πrl = 1/3 (π×7×25)= 1/3 ×549.78

=183.26 cm³

Answer:9

Step-by-step explanation:

3/4 times 12=3(12/4)=3x3=9

Another way:

3/4=0.75

0.75x12=9

9 that's your answer your welcome

Answer:

Hi, I love these types of questions. So, ima teach you how to find the answer. If your only looking for an answer, skip to the bottom. So, what your trying to find is the solution to 3/10 divided by 6/11. So, remember, copy, dot, flip.

Copy- Copy the equation- 3/10 6/11

Dot- Change the division sign to multiplication- 3/10 X 6/11

Flip- so, this is where it gets a bit tricky. You wanna flip the numerator and denominator on the second fraction- 3/10 X 11/6

now multiply across-

33/60

simplify

11/20

Your answer is 11/20

It says that there was an error with my answer, but I don't know what, so I screenshotted what I typed and attached them as 4 images below:

Answer:

D

Step-by-step explanation:

To solve this you can just plug in the x values into the equation and if the answer is correct the y value should be your answer

For example if we look at D

we can plug in 2 for y=5x and get 10

We can see that the y value in the ordered pair is also 10 making this the correct answer

kind of hard to explain if you have any questions leave a comment

Answer:

D

Step-by-step explanation:

y= 5x

10= 5(2)

10=10

Ha?what do you mean ba? Jjsjsjsjjsjs

Answer:

what did you say???????

Answer:

112 degrees

Step-by-step explanation:

This is a quadrilateral, meaning 4 sides. The sum of the angles of a quadrilateral is 360 degrees. You are given the right angle, or 90 degrees, and the 46 degree angle at the bottom. Since the two lines on either side of the 46 degree angle represent parallelism, angles 1 and 2 are the same.

360 - (90+46) = 224.

224 / 2 = 112.

Answer:

[tex]m∠1 = 112[/tex]

Step-by-step explanation:

[tex]m∠1 = m∠2[/tex]

[tex]m∠1 + m∠2 + 90 + 46 = 360[/tex]

[tex]m∠1 +m ∠2 + 136 = 360[/tex]

[tex]m∠1 + m∠2 = 360 - 136[/tex]

[tex]m∠1 + m∠2 = 224[/tex]

[tex]m∠1 = \frac{224}{2} [/tex]

[tex]m∠1 = 112[/tex]

[tex]m∠2 = \frac{224}{2} [/tex]

[tex]m∠2 =112[/tex]

Answer:

The answer is the last one!

Step-by-step explanation:

x is the domain and y is the relation

-Sumin <3

Step-by-step explanation:

[tex]y = 4x - 4 \\ x + y = 11 \\ x + 4x - 4 = 11 \\ 5x = 15 \\ x = 3 \\ y = 4 \times 3 - 4 \\ y = 8[/tex]

Answer:70 should be the angle

Step-by-step explanation:  3x2+4x2=20

LIKE if this helped

Answer:

m∡B = 37°

Step-by-step explanation:

since this is a right triangle you can use the trigonometric ratios of

sin, cos, or tan

in this problem, we know opp/adj so can use tangent

tan(∠B) = 3/4

tan^-1(3/4) = 36.8°

Answer:

x=2

Step-by-step explanation:

-2x+4=6x-12  Add 2x to both sides.

+2x    +2x

4=8x-12         Add 12 to both sides.

+12  +12

16=8x            Divide by 8 on both sides.

/8 /8

2=x

Hope this helps you out and have a great day (～^▽^)～

Answer:

x=2

Step-by-step explanation:

-2x + 4 = 6x - 12

First add 2x to each side: 4=6x−12+2x

Now simplify 6x-12+2x: 4=8x-12

add 12 to both sides: 4+12=8x

Simplify 4+12: 16=8x

Divide both sides by 8: 16/8

you end up with x=2

Hope this helps :)
