Answer:

Simplify 3(x+1)−5.

3x−2=3x−2

Move all terms containing x to the left side of the equation.

−2=−2 Since −2=−2 , the equation will always be true for any value of x

All real numbers

The result can be shown in multiple forms.

All real numbers

Interval Notation:

(−∞,∞)

Option2 : infinite solutions

Use the quadratic formula to solve x^2+8x+9=0
Tju [1.3M]
None of your options, not via complete the square nor quadratic the formula.

Solve for x over the real numbers:
x^2 + 8 x + 9 = 0

x = (-8 ± sqrt(8^2 - 4×9))/2 = (-8 ± sqrt(64 - 36))/2 = (-8 ± sqrt(28))/2:
x = (-8 + sqrt(28))/2 or x = (-8 - sqrt(28))/2

sqrt(28) = sqrt(4×7) = sqrt(2^2×7) = 2sqrt(7):
x = (2 sqrt(7) - 8)/2 or x = (-2 sqrt(7) - 8)/2

Factor 2 from -8 + 2 sqrt(7) giving 2 (sqrt(7) - 4):
x = 1/22 (sqrt(7) - 4) or x = (-2 sqrt(7) - 8)/2

(2 (sqrt(7) - 4))/2 = sqrt(7) - 4:
x = sqrt(7) - 4 or x = (-2 sqrt(7) - 8)/2

Factor 2 from -8 - 2 sqrt(7) giving 2 (-sqrt(7) - 4):
x = sqrt(7) - 4 or x = 1/22 (-sqrt(7) - 4)

(2 (-sqrt(7) - 4))/2 = -sqrt(7) - 4:

Answer: x = sqrt(7) - 4 or x = -sqrt(7) - 4_____________________________________________________

Solve for x:
x^2 + 8 x + 9 = 0

Subtract 9 from both sides:
x^2 + 8 x = -9

Add 16 to both sides:
x^2 + 8 x + 16 = 7

Write the left hand side as a square:
(x + 4)^2 = 7

Take the square root of both sides:
x + 4 = sqrt(7) or x + 4 = -sqrt(7)

Subtract 4 from both sides:
x = sqrt(7) - 4 or x + 4 = -sqrt(7)

Subtract 4 from both sides:
Answer:  x = sqrt(7) - 4 or x = -4 - sqrt(7)

If line segment ab=7cm draw a perpendicular at a point c on line ab such the ac=3.5cm
Reil [10]

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

<h3>How to draw the perpendicular at a point c on line ab such the ac = 3.5 cm?</h3>

The given parameters are:

Length of segment AB = 7 cm

Also, we have:

Point C is located on line segment AB

This means that:

Length of segment AC = Length of segment BC = 3.5 cm

When represented on a line segment, we have:

A          C          B

See attachment for the drawing of the perpendicular at a point c on line ab such the ac = 3.5 cm

Joey wrote a book about his favorite Author.
Rasek [7]

Answer: $6000

Step-by-step explanation:

Multiply the cost of the book by the decimal equivalent of 12% (25 x .12).  this equal 3 dollars per book.  2,000 copies of the book were sold, so you would multiply 2000 by 3.  2000 x 3 = 6000
