Answer:

-12 =x

Step-by-step explanation:

3(x - 2) = 6(5 + x)

Distribute

3x -6 = 30 +6x

Subtract 3x from each side

3x-6-3x = 30 +6x-3x

-6 = 30+3x

Subtract 30 from each side

-6 -30 = 30+3x-30

-36 = 3x

Divide each side by 3

-36/3 = 3x/3

-12 =x

Step-by-step explanation:

For an even-index radical, ...

$\sqrt[n]{x^n}=|x|\qquad\text{n even}$

This lets us simplify the given expression as follows:

$\sqrt[4]{81x^6y^4}-|y|\sqrt[4]{x^6}-\sqrt[4]{16x^2}=\sqrt[4]{(3xy)^4x^2}-|y|\sqrt[4]{x^4x^2}-\sqrt[4]{2^4x^2}\\\\=3|xy|\sqrt[4]{x^2}-|xy|\sqrt[4]{x^2}-2\sqrt[4]{x^2}=\boxed{2|xy|\sqrt[4]{x^2}-2\sqrt[4]{x^2}}$

Answer:

(x, y) = (-2, -3)

WORK:

2x + 4y = -16 =

-2x + 2y = -2 =

(^ the two’s cancel out) =

6y = -18 =

(^ you need to divide 6 on both sides to get just y) =

6y/6 = -18/6 =

(^ the six’s cancel out) =

y = -3 =

(^ now you have to plug this in to get x) =

2x + 4(-3) = -16 =

2x - 12 = -16 =

(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =

2x = -4 =

2x/2 = -4/2 =

(^ now you divide 2 on both sides again to get just y, and they will cancel out) =

x = -2 =

THEREFORE YOU GET (-2, -3)

Find the missing angle measure. then classify the triangle by its angles and by its sides.

iren [92.7K]

Answer:

Part a) The measure of the missing angle is $90\°$

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to $180\°$

Let

x------> the missing angle

we know that

$x\°+50\°+40\°=180\°$

solve for x

$x=180\°-90\°=90\°$

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of $90\°$

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different

How do you simplify (-1 - 3 √(3) × (-1 - 3 √(3)

harina [27]

Answer:

4 + 6√(3)

Step-by-step explanation:

Two right parentheses seem to be missing here. I think you meant:

(-1 - 3 √(3) ) × (-1 - 3 √(3) )

and this is the square of a binomial. The resulting square is:

1 + 6√3 + 3, or 4 + 6√(3)
