What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
X2 + 23x – 19 = 9x - 4
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

Which point represents the quotient of 4+3i/-i
Answer: Point C.
Step-by-step explanation:
Point B represents the quotient of 4+3i/-i.
What is a complex number?Complex numbers are the numbers that are expressed in the form of
a + ib where, a, b are real numbers and 'i' is an imaginary number called “iota”.
Given complex number
[tex]\frac{4+3i}{-i}[/tex]
= [tex]\frac{4+3i}{-i} \times \frac{i}{i}[/tex]
= [tex]\frac{4i+3i^{2} }{-i^{2} }[/tex]

PLEASE HELP. urgent. What is the answer? HELP please!
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

In the diagram shown overline AD and intersect at point E. overline AB and overline CD are parallel . Given the segment length shown in the picture, which of the following is the length overline AE
1) 11.25
2) 10.8
3) 10
4) 7.5
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

Find the measure of A. No links!!!!
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.

The mean of six numbers is 8, and the mean of another four numbers is 5.
What is the mean of all ten numbers?
Answer:
6.8
Step-by-step explanation:
8 * 6 = 48 (to reverse dividing by 6 to basically un-average the 6 numbers).
5 * 4 = 20 (to un-average these numbers as well).
48 + 20 = 68
68 / 10 = 6.8
Basically by doing this you are still adding all the numbers together & then dividing by 10 as if you added them all up at once & not in a group of 6 & a group of 4.

Find sin(β) in the triangle.
Answer:
4/5
Step-by-step explanation:
Given :-
A right angled triangle with sides as 3 , 4 and 5 cm .We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,
[tex]:\implies[/tex] sin(β) = p/h
Where p is perpendicular and h is hypontenuse.[tex]:\implies[/tex] sin(β) = 4/5
Hence the required answer is 4/5.The measures of interior angle of a convex pentagon are in ratio 1:2:3:4:5. Find the measures of each angle
Answer:
The angles have measurements 36, 72, 108, 144, and 180.
Step-by-step explanation:
Pentagon has 5 sides and 5 angles.
The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.
3(180)=540 which is the sum of the angles in a pentagon.
So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.
We have the equation 1x+2x+3x+4x+5x=540 to solve.
15x=540
Divide 15 on both sides:
x=540/15
x=36
1x=36
2x=72
3x=108
4x=144
5x=180
The angles have measurements 36, 72, 108, 144, and 180.

Simplify the expression 2√6 -5√54
Answer:
- 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]
