3x+6=-3(2x+4) Show your work

Lera25 [3.4K]

Answer:

$\boxed {x = -2}$

Step-by-step explanation:

Solve for the value of $x$ :

$3x + 6 = -3(2x + 4)$

-Use Distributive Property:

$3x + 6 = -3(2x + 4)$

$3x + 6 = -6x - 12$

-Take $6x$ and add it to $3x$ :

$3x + 6 + 6x = -6x + 6x - 12$

$9x + 6 = -12$

-Subtract both sides by $6$ :

$9x + 6 - 6 = -12 - 6$

$9x = -18$

-Divide both sides by $9$ :

$\frac{9x}{9} = \frac{-18}{9}$

$\boxed {x = -2}$

Therefore, the value of $x$ is $-2$ .

Calculate the perimeter of an equilateral triangle which has a side of 14cm

g100num [7]

An equilateral triangle has 3 equal sides. Since one side is 14 cm, then all sides are 14 cm. You multiply 4 by 3 and you get your answer.

14*3=42. The perimeter is 42cm.
