Answer:

Explanation:

<em>Write your equation</em>

(3x + 14) = (9x - 4)

<em>Subtract 9x from both sides</em>

3x + 14 − 9x = 9x − 4 − 9x

−6x + 14 = −4

<em>Subtract 14 from both sides</em>

−6x + 14 − 14 = −4 − 14

−6x = −18

<em>Divide both sides by -6</em>

−6x / -6 = −18 / -6

Answer:

x=3

Step-by-step explanation:

Simplifying

9x + -4 = 3x + 14

Reorder the terms:

-4 + 9x = 3x + 14

Reorder the terms:

-4 + 9x = 14 + 3x

Solving

-4 + 9x = 14 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-4 + 9x + -3x = 14 + 3x + -3x

Combine like terms: 9x + -3x = 6x

-4 + 6x = 14 + 3x + -3x

Combine like terms: 3x + -3x = 0

-4 + 6x = 14 + 0

-4 + 6x = 14

Add '4' to each side of the equation.

-4 + 4 + 6x = 14 + 4

Combine like terms: -4 + 4 = 0

0 + 6x = 14 + 4

6x = 14 + 4

Combine like terms: 14 + 4 = 18

6x = 18

Divide each side by '6'.

x = 3

Simplifying

x = 3

The perimeter of a trapezoid is 39a – 7. Three sides have the following lengths: 9a, 5a + 1, and 17a – 6. What is the length of

Airida [17]

We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve
C. 8a-2=4th side is the correct answer

The rectangle below has an area of x^2 - 9 square meters and a width of x - 3 meters.

Rama09 [41]

Answer:

x+3

Step-by-step explanation:

Area of a rectangle is $L\cdot W$ .

We know the width, W, is $x-3$ and we know the area is $x^2-9$ .

Inputting this in our formula above we get:

$x^2-9=L(x-3)$

L is a an expression such that when you multiply it to $(x-3)$ gives you $(x^2-9)$ .

$x^2-9$ is a difference of squares and can be factored using:

$a^2-b^2=(a-b)(a+b)$ .

$x^2-9=(x-3)(x+3)$ .

So L=x-3 and W=x+3.

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra

luda_lava [24]

The surface area of a sphere is $A = 4 \pi r^{2}$ and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.

For example, let us assign values.
Let A=90

A= 90*9 = 810

$90 = 4 \pi r^{2} 

$ and $810 = 4 \pi r ^{2}$

the first r is 2.68 and the second r is 8.03

then, $\frac{8.03}{2.68} = 2.99626$ or rounded off to 3.
