Answer:

x = -2

Step-by-step explanation:

6(3x + 4) = 4x − 4

Distribute:

18x + 24 = 4x - 4

18x - 4x + 24 = -4

14x + 24 = -4

14x = -4 - 24

14x = -28

x = -28 / 14

x = -2

Answer:

x = - 2

Step-by-step explanation:

Given

6(3x + 4) = 4x - 4 ← distribute parenthesis on left side

18x + 24 = 4x - 4 ( subtract 4x from both sides )

14x + 24 = - 4 ( subtract 24 from both sides )

14x = - 28 ( divide both sides by 14 )

x = - 2

Find the discriminant and the numbers of real roots for this equation: 4x^2+12x+9=0
Len [333]

Answer:

D=0

The quadratic equation has one real root with a multiplicity of 2.

Step-by-step explanation:

Given a quadratic equation:

 ax^2+bx+c=0

You can find the Discriminant with this formula:

D=b^2-4ac

<em> </em>In this case you have the following quadratic equation:

4x^2+12x+9=0

Where:

a=4\\b=12\\c=9

Therefore, when you substitute these values into the formula, you get that the discriminant is this:

D=(12)^2-4(4)(9)\\\\D=0

Since D=0, the quadratic equation has one real root with a multiplicity of 2 .

Find the surface area of the composite solid.
Scilla [17]

Answer with Step-by-step explanation:

The given figure is a cuboid.

We know that surface area(S) of cuboid is given by:

S=2(lb+bh+hl)

Where l is the length, b is the breath and h is the height

Here, l=12 mm

         b=6 mm

and h=(7+2) mm=9 mm

Surface Area= 2(12×6+6×9+9×12)

                    =2(72+54+108)

                   = 2×234

                   = 468 mm²

Hence, Correct option is:

C. 468 mm squared
