Answer:

(x + 7)^2 = 64

Step-by-step explanation:

x^2 + 23x – 19 = 9x - 4

x^2 + 23x - 9x = -4 + 19

x^2 + 14x = 15 = 0

Completing the square:

(x + 14/2)^2 - (14/2)^2 = 15

(x + 7)^2 - 49 = 15

(x + 7)^2 = 64

Answer:

y=1/6x+5

Step-by-step explanation:

m represents the slope

y=1/6x+b

now we have to find b

plug in y and x

5=0+b

b=5

Answer:

surface area is- 198 and volume is 162

Step-by-step explanation:

(4,10) + (10,16) are different rates.

Answer:

A equals 105 degrees, option 2

Step-by-step explanation:

7x + 5x gives 180. 7x and 5x lie on a line so they form a linear pair. Their sum equals 180 degrees:-

7x + 5x = 180

12x = 180

x = [tex]\frac{180}{12}[/tex]

x = 15

Since x is 15, we can find the lengths of 7x and 5x.

7x would be 7 x 15 = 105

5x would be 5 x 15 = 75

'A' is equal to 7x since they are vertically opposite angles.

Since 7x is 105 degrees, then A would be 105 degrees as well.

- 13[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying [tex]\sqrt{54}[/tex]

[tex]\sqrt{54}[/tex]

= [tex]\sqrt{9(6)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{6}[/tex]

= 3[tex]\sqrt{6}[/tex]

Then

2[tex]\sqrt{6}[/tex] - 5[tex]\sqrt{54}[/tex]

= 2[tex]\sqrt{6}[/tex] - 5 (3[tex]\sqrt{6}[/tex] )

= 2[tex]\sqrt{6}[/tex] - 15[tex]\sqrt{6}[/tex]

= - 13[tex]\sqrt{6}[/tex]

Answer:

C : Parallel lines are always in the same plane.

Step-by-step explanation:

Parallel lines must be coplanar

Answer:

The answer is, parallel line are always in the same plane.

Step-by-step explanation:

Lines in a plane that are always the same distance apart are called parallel lines. Parallel lines do not cross.

A - Perpendicular lines must always cross at least once.

B - Parallel lines should never cross.

D- This isn't always the case.

C is true.

Skewed lines are those that are not in the same plane.

8.68 × 10^8

Step-by-step explanation:

--------------------

Answer:

8.68x10^8

Step-by-step explanation:

move 8 times to the left

From the figure, we can notice that : Surface area of the pyramid is equal to Sum of the area of the square and Sum of the areas of 4 triangles.

We know that : Area of a square is given by : Side x Side

Given : Side of the square = 3 cm

⇒  Area of the square = 3 x 3 = 9 cm²

We know that : Area of the triangle = 1/2 x Base x Height

From the figure, We can notice that, Base of each triangle = 3 cm and height of the each triangle = 3 cm

⇒ Area of one triangle = 1/2 × 3 × 3 = 4.5 cm²

Surface area of the pyramid = Surface of the square + Surface area of the 4 triangles

⇒  Surface area of the pyramid = 9 cm² + 4(4.5) cm²

⇒  Surface area of the pyramid = 9 cm² + 18 cm² = 27 cm²

Answer : Surface area of the pyramid = 27 cm²

Answer:

11.25

Step-by-step explanation:

Since AB and CD  are parallel, ∠D is congruent to ∠A and ∠C is congruent to ∠B.  Therefore the two triangles are similar by the AA postulate.  Now, the corresponding sides are in proportion

Since AE ↔ DE and AB ↔ CD

So, AE/CD = AB/CD

AE/5 = 9/4

AE = 9(5)/4

     = 45/4  = 11.25
