-7x - 12 = - 7х + 3(-4 - x)

dsp73

Answer:

$x=0$

Step-by-step explanation:

$-7x - 12 = - 7x + 3(-4 - x)$

Open up the parentheses

$-7x - 12 = - 7x -12-3x$

-7x cancels out on both sides

$-12 =-12-3x$

-12 cancels out on both sides

$0=-3x\\x=0$

I hope this helps!

Given the sequence 8, 12, 16, 20, 24, what is the sum of the 31st and 19th terms?

erica [24]

Answer:

First term (a) =8

Common difference (d)= t2-t1

=12-8

Now, sum of first 31th term (tn31) =n/2{2a+(n-1)d}

= 31/2{2×8+(31-1)4}

=31/2{16+(30×4)

=31/2(16+120)

=31/2×126

=31×63

Step-by-step explanation:

Similarly use 19 as (n) for the 19th term

How do you find the arc length in a circle given any angle?

Nataly_w [17]

You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.

Use five different colors to paint the four rectangles A, B, C and D shown in the figure. No two rectangles sharing an edge can

GenaCL600 [577]

There are 120 ways to color the 4 rectangles

<h3>How to determine the number of ways?</h3>

The given parameters are:

Paints, n = 5

Rectangles, = 4

The number of ways to color the rectangles is

$Ways = ^nP_r$

This gives

$Ways = ^5P_4$

Apply the permutation formula

$Ways = \frac{5!}{1!}$

Evaluate the expression

Ways = 120

Hence, there are 120 ways to color the 4 rectangles
