Solve for x 4(x + 2) = 3 (x - 2)

Answers

Answer:

x = -14

)Step-by-step explanation:

To find the value of x

Transpose

4(x + 2) = 3 (x - 2)

4x + 8 = 3x - 6

4x - 3x = -6 -8

x = -14

we can even cross check

putting the value of x by -14

4(x + 2) = 3 (x - 2)

4 (-14 +2) = 3 (-14 -2)

-56 +8 = -42 -6

-48 = -48

same = same

so CROSS-CHECKED

Answer:

x = -14

Step-by-step explanation:

4(x + 2) = 3 (x - 2)

4x + 8 = 3x - 6

x + 8 = -6

x = -14

Maggie's brother is 4 years younger than twice her age. The sum of their ages is 29.
How old is Maggie?
Maggie is____
years old.

Answers

Answer:

11

Step-by-step explanation:

You have to make a system of equations. So the first equation would be b=2m-4 (b is brother m is maggie). The next equation is 29=m+b (sum of their ages). Then you can use substitution so plug in 2m-4 for b in the second question. So it would be 29=m+2m-4. Simplify and solve for m and you get 11.

Answers

Answer:

  x = 2, x = 6

Step-by-step explanation:

The quadratic can be factored as ...

  x^2 -8x +12 = 0

  (x -2)(x -6) = 0

Solutions are the values of x that make these factors zero:

  x -2 = 0   ⇒   x = 2

  x -6 = 0   ⇒   x = 6

The hypotenuse of a right triangle is 10 meters and its
legs measure x and x + 2. How long are the legs?

Answers

Solution :

Let's solve by using Pythagoras theorem,

[tex] \hookrightarrow \: (10) {}^{2} = {(x})^{2} + (x + 2) {}^{2} [/tex]

[tex] \hookrightarrow \: 100 = {x}^{2} + {x}^{2} + 4x + 4[/tex]

[tex] \hookrightarrow \: 100 - 4 = 2 {x}^{2} + 4x[/tex]

[tex] \hookrightarrow \: 96 = 2 {x}^{2} + 4x[/tex]

[tex] \hookrightarrow \: 2 {x}^{2} + 4x - 96 = 0[/tex]

[tex] \hookrightarrow \: 2( {x}^{2} + 2x - 48) = 0[/tex]

[tex] \hookrightarrow \: {x}^{2} + 2x - 48 = 0[/tex]

[tex] \hookrightarrow \: {x}^{2} + 8x - 6x - 48 = 0[/tex]

[tex] \hookrightarrow \: x(x + 8) - 6(x + 8) = 0[/tex]

[tex] \hookrightarrow \: (x + 8)(x - 6) = 0[/tex]

now there are two cases

Case 1 : when (x + 8) = 0

[tex] \hookrightarrow \: x + 8 = 0[/tex]

[tex] \hookrightarrow \: x = - 8[/tex]

but the value of x can't be negative, since side of a triangle isn't a negative value .

Case 2 : when (x - 6) = 0

[tex] \hookrightarrow \: x - 6 = 0[/tex]

[tex] \hookrightarrow \: x = 6[/tex]

therefore the measure of other two sides are :

[tex] \hookrightarrow \: x = 6 \: units[/tex]

[tex] \hookrightarrow \: x + 2 = 6 + 2 = 8 \: units[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \mathrm{TeeNForeveR } [/tex]
