Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below. (3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2) = 3y2 – 12y2 = –9y

Lilit [14]

No he's not correct

(3 – 6y2)(y2 + 2)
= 3(y2) -6(y2)(y2) - 6y2(2) + 3(2)
= 3y2 -6y4 - 12y2 + 6 
= -6y4 - 9y2 +6

What value of x makes the following equation true? 15+3x=3(2−2x)

Alinara [238K]

Answer:

$\boxed {x = -1}$

Step-by-step explanation:

Solve for the value of $x$ :

$15 + 3x = 3(2 - 2x)$

-Use Distributive Property:

$15 + 3x = 3(2 - 2x)$

$15 + 3x = 6 - 6x$

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

$15 + 3x + 6x = 6 + 6x - 6x$

$15 + 9x = 6$

-Subtract both sides by $15$ :

$15 - 15 + 9x = 6 - 15$

$9x = -9$

-Divide both sides by $9$ :

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

$\boxed {x = -1}$

Therefore, the value of $x$ is $-1$ .
