2 + 4(3+2x) = 3x + 8

2 + 12 + 8x = 3x + 8

14 - 8 = 3x - 8x

6 = -5x

x = -6/5

 2 + 4 ( 3 + 2x ) = 3x + 8
 2 + 12 + 8x = 3x + 8
14 + 8x = 3x + 8
 8x - 3x = 8 - 14
 5x = -6
 x = -1.2

hope this helps

In a triangle shown, which shows the correct order of the side lengths from smallest to largest.
Vera_Pavlovna [14]

Answer:

Not sure if there are options, but the order of side lengths from smallest to largest is <u>j, k, l</u>

Step-by-step explanation:

This is a bad explanation (sorry):

Side length order will be the same order of angle orders. By that, I mean the since angle C has the smallest angle, the side length across from it will also be the smallest. Since angle B is the biggest angle, side L will be the biggest length. This leaves angle A (and side k) in the middle.

A firm manufactured 1000 Tv sets during its first yeae the total firns production during 10 years of operation is 29035 sets If
Alexus [3.1K]

Answer: the increase each year is 423 tv sets

Step-by-step explanation:

The formula for determining the sum of n terms of an arithmetic sequence is expressed as

Sn = n/2[2a + (n - 1)d]

Where

n represents the number of terms in the arithmetic sequence.

d represents the common difference of the terms in the arithmetic sequence.

a represents the first term of the arithmetic sequence.

From the information given,

n = 10 years

a = 1000

S10 = 29035

We want to determine d which is the amount by which the production increased each year. Therefore, the sum of the first 10 years would be

29035 = 10/2[2 × 1000 + (10 - 1)d]

29035 = 5[2000 + 9d]

29035/5 = [2000 + 9d]

9d = 5807 - 2000 = 3807

d = 3807/9 = 423
