Find the value of x.

Answer:

x=4,−2

Step-by-step explanation:

Because Step 1. Move all terms to one side.

{x}^{2}-2x-8=0

x

2

−2x−8=0

2 Factor {x}^{2}-2x-8x

2

−2x−8.

1 Ask: Which two numbers add up to -2−2 and multiply to -8−8?

-4−4 and 22

Step 2. Rewrite the expression using the above.

(x-4)(x+2)

(x−4)(x+2)

and going to;

(x-4)(x+2)=0

(x−4)(x+2)=0

And Step 3. Solve for xx.

1 Ask: When will (x-4)(x+2)(x−4)(x+2) equal zero?

When x-4=0x−4=0 or x+2=0x+2=0

2 Solve each of the 2 equations above.

x=4,-2

x=4,−2

x=4,-2

Our Answer is:

x=4,−2

tso numbers when added gives -2 and 8 incase it's not clear enough.

Answer:

494018

Step-by-step explanation:

you are trying to find the diameter of the circle, it is usually half the length of a radius, but since 497 squared is how long a radius is (unless the question asked that the area if 497 inches squared), i can't really give you a clear answer, but the diameter is 247009 times 2 which is 494018

Answer:

y = 7/2 x+16

Step-by-step explanation:

The equation for a line is y = mx+b where m is the slope and b is the y intercept

y = 7/2 x+b

Substitute the point into the equation

9 = 7/2(-2)+b

9 = -7+b

9+7 = b

16 = b

y = 7/2 x+16

Answer:

x = 0.6

Step-by-step explanation:

2(x+4)+8x = 14

2x+8+8x = 14

10x+8 = 14

10x = 6

(divide by 10)

x= 0.6

By AAS criteria, ΔABC ≅ ΔADC.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is CA bisects ∠BAD, AB ⊥ BC and AD ⊥ DC.

In ΔABC and ΔADC -

∠ABC = ∠ADC = 90°

∠ACB = ∠ACD     {bisected angle ∠BCD}

AC = AC  {Common}

By AAS criteria, ΔABC ≅ ΔADC.

Therefore, by AAS criteria, ΔABC ≅ ΔADC.

Answer:

Option (3)

Step-by-step explanation:

Since, flowerbed is in the shape of a right triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(Hypotenuse)² = (12)² + (12)²

(Hypotenuse)² = 144 + 144

Hypotenuse = √288

Hypotenuse = 16.97

                     ≈ 17 ft

Perimeter of the triangle = Sum of the measures of three sides of the triangle

= 12 + 12 + 17

= 41 ft

Therefore, Option (3) will be the correct option.

Answer:

41ft

Answer:

$45

Step-by-step explanation:

If it looses it value of 14 % every year, by the end of 5 years, the value would go down by 70%.  So, 150x0.7= 105, 150-105=45, so it would be. worth. 45% in 5 years.

Answer: The number of people can be expected to have cold = 34

Step-by-step explanation:

Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.

If a doctor sees 40 patients, then the number of people can be expected to have cold = [tex]40\times\dfrac{6}{1+6}[/tex]

[tex]=40\times\dfrac6{7}[/tex]

[tex]=\dfrac{240}{7}\\\\=34.29\approx34[/tex]

Hence, the number of people can be expected to have cold = 34

Answer:

∠ 2 = 104°

Step-by-step explanation:

- 8x - 48 = 9x + 275               [ alternate angles are equal ]

-8x - 9x = 275 + 48

-17x = 323

x = -19  

9x + 275 = 9 × -19 + 275

             = - 171 + 275

             = 104°

∠ 2 = ( 9x + 275 )                                     [vertically opposite angles ]

∠ 2 = 104°
