What is the intermediate step in the form (x + a)2 = b as a result of
completing the square for the following equation?
3x2
42x
-120

Answer:

5. a = 4

7. x = -8

9. x = -1

11. p = 1.1

13. x = -1

15. x = -4

Step-by-step explanation:

2.9a = 11.6

2.9a/2.9 = 11.6/2.9

a = 4

-3.7x = 29.6

-3.7x/-3.7 = 29.6/-3.7

x = -8

(x-5)(-3) = 18

(x-5)(-3)/-3 = 18/-3

x-5 = -6

x-5+5 = -6+5

x = -1

3.6 = -2p+5.8

3.6-5.8 = -2p+5.8-5.8

-2.2 = -2p

-2.2/-2 = -2p/-2

1.1 = p

2x+6 = -4x

2x+6-6 = -4x-6

2x = -4x-6

2x+4x = -4x-6+4x

6x = -6

6x/6 = -6/6

x = -1

21-6x = -11-14x

21-6x-21 = -11-14x-21

-6x = -14x-32

-6x+14x = -14x-32+14x

8x = -32

8x/8 = -32/8

x = -4

Answer:

5.) a= 4

7.) x= -8

9.)x= -1

11.) p= 1.1

13.) x= -1

15.) x= -4

Step-by-step explanation:

5.) divide 11.6 by 2.9a

7.)divide 29.6 by -3.7u

9.) Divide by sides by -3. simplify. Add 5 to both sides. then simplify again x= -1

11.) subtract 5.8 from 3.6 . you're left with -2p=-2.2 divide both sides by -2. you get p=1.1

13.)Subtract 6 from both sides. You get 2x= -4x-6. Add 4x to both sides. then divide -6 by 6 you get x=-1

15.) Simplify both sides of the equation, so add 14x to -6x +21 side, you get 8x= -32 then divide -32 by 8x you get -4

Step-by-step explanation:

The value of x', the image point with respect to an axis rotated 60 is 3/2 + 4√3

The point is given as:

(x, y) = (3, 8)

The angle of rotation is given as:

θ = 60

The image of rotation is calculated using:

x = x'cosθ - y'sinθ

y = x'sinθ + y'cosθ

So, we have:

3 = x'cos(60) - y'sin(60)

8 = x'sin(60) + y'cos(60)

Evaluate cos(60) and sin(60)

3 = 1/2x' - y'√3/2

8 = x'√3/2 + 1/2y'

Multiply the second equation by √3

8√3 = 3/2x' + √3/2y'

Add this equation and the first equation to eliminate y'

3 + 8√3 = 1/2x' + 3/2x'

Evaluate the sum

3 + 8√3 = 2x'

Divide through by 2

x' = 3/2 + 4√3

Hence, the value of x' is 3/2 + 4√3

Answer:

A) -30 - x = 10 and -30 - x = –10

Step-by-step explanation:

Part 1:

1) Isolate the variable x

-30 - x = 10

-x = 40

2) Multiply both sides by -1

x = -40

Therefore -30 - x = 10 is correct

Part 2:

1) Isolate the variable x

-30 - x = –10

-x = 20

2) Multiply both sides by -1

x = -20

Therefore -30 - x = –10 is also correct

Final Answer: -30 - x = 10 and -30 - x = –10

In the right ABC above, the length of the side BC is 4.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

Given;

Side BA= [tex]\sqrt{11}[/tex]

Side AC= [tex]\sqrt{5}[/tex]

BC^2=BA^2+AC^2

BC^2= ([tex]\sqrt{11}[/tex])^2 +([tex]\sqrt{5}[/tex])^2

BC^2= 11+5

BC^2= 16

BC= 4

Therefore, the Pythagoras theorem gives answer 4
