1)a parallelogram is a quadrilateral with opposite sides being parallel so the lines AB must equal CD or otherwise it wouldn't be a parallelogram

2)for a quadrilateral to be proven to be a parallelogram the consecutive angles has to be supplementary which means they add up to 180 or for example you could slice the parallelogram in half down the middle you could piece the two consecutive angles together to make 180 degrees

What is a formula for the nth term of a given sequence

IceJOKER [234]

Answer:

$a_n=-12-4(n-1)$

Step-by-step explanation:

The given sequence is

-12,-16,-20...

The first term of this sequence is $a_1=-12$ .

The common difference is

$d=-16--12$

$d=-16+12=-4$

The nth term of this arithmetic sequence is;

$a_n=a_1+d(n-1)$

We substitute the values for the first term and the common difference to obtain;

$a_n=-12-4(n-1)$

What is the volume of a sphere with a radius of 3 inches? 12π cubic inches 24π cubic inches 36π cubic inches 48π cubic inches

Anni [7]

Answer:

The answer is

<h2>36π cubic inches</h2>

Step-by-step explanation:

Volume of a sphere is given by

<h3> $V = \frac{4}{3} \pi {r}^{3}$ </h3>

where r is the radius

From the question

r = 3 inches

Substitute the value into the above formula and solve for the volume

That's

<h3> $V = \frac{4}{3}( {3})^{3} \pi \\ = \frac{4}{3} \times 27\pi \\ = 4 \times 9\pi$ </h3>

We have the final answer as

<h3>36π cubic inches</h3>

Hope this helps you

Solve (x + 6)/x - 4) = -16<br> 0 (-12. 22)<br> 0 1-4. 2)<br> O {-4. 6)

Snowcat [4.5K]

Answer:

$3\frac{7}{17}$

Step-by-step explanation:

$\frac{(x + 6)}{(x - 4)} = - 16 \\ \\ x + 6 = - 16(x - 4) \\ x + 6 = - 16x + 64 \\ x + 16x = 64 - 6 \\ 17x = 58 \\ x = \frac{58}{17} \\ x = 3\frac{7}{17} \\$
