Answer:

6(2x - 1)

Step-by-step explanation:

Given

12x - 6 ← factor out common factor of 6 from both terms

= 6(2x - 1) ← in factored form

6(2x-1)
Because you multiply the 6 by 2X and the answer will be 12X

Find the sum of the first 8 terms in the geometric sequence: 1, 3, 9, 27,

Butoxors [25]

The sum of the first 8 items in the geometric sequence:1, 3, 9, 27, ...etc is 3280.

Step-by-step explanation:

The given is,

sequence: 1,3,9,21,.. etc

Step:1

The given is based on multiplication of 3 to previous number,

( x - previous number, next number = 3 × $x$ )

First term : 1

Second term : 1 × 3 = 3

Third term : 3 × 3 = 9

Fourth term : 9 × 3 =27

Fifth term : 27 × 3 = 81

Sixth term : 81 × 3 = 243

Seventh term : 243 × 3 = 729

Eighth term : 729 × 3 = 2187

Step:2

Sum of first 8 terms $= 1 + 3 + 9 + 27 + 81 + 243 + 729 + 2187$

= 3280

Sum of first 8 terms = 3280

Result:

The sum of the first 8 items in the geometric sequence:1, 3, 9, 27, ...etc is 3280.

In a baseball league consisting of 15 teams, each team plays each of the other teams three times. How many games will be played

denis23 [38]

Answer:

315

Step-by-step explanation:

Each of the 15 teams plays each of the other 14, for a total of 210 games. However, that count includes both A playing B and B playing A. Hence, if the teams meet 3 times, the total number of games will be 3/2 this amount:

(15)(14)(3/2) = 315 . . . league games

A rectangular field on a farm is to be fenced in using the wall of the barn for one side and 200 meters of fencing for the other

vitfil [10]

Answer:

Rectangular area as a function of x : A(x) = 200*x + 2*x²

A(max) = 5000 m²

Dimensions:

x = 50 m

l = 100 m

Step-by-step explanation:

"x" is the length of the perpendicular side to the wall of the rectangular area to be fenced, and we call "l" the other side (parallel to the wall of the barn) then:

A(r) = x* l and the perimeter of the rectangular shape is

P = 2*x + 2*l but we won´t use any fencing material along the wll of the barn therefore

P = 2*x + l ⇒ 200 = 2*x + l ⇒ l = 200 - 2*x (1)

And the rectangular area as a function of x is:

A(x) = x * ( 200 - 2*x) ⇒ A(x) = 200*x + 2*x²

Taking derivatives on both sides of the equation we get:

A´(x) = 200 - 4*x ⇒ A´= 0

Then 200 - 4*x = 0 ⇒ 4*x = 200 ⇒ x = 50 m

We find the l value, plugging the value of x in equation (1)

l = 200 - 2*x ⇒ l = 200 - 2*50 ⇒ l = 100 m

A(max) = 100*50

A(max) = 5000 m²
