The solution to this is x=5,4 and -1. Does anyone know how to explain this to me? It would be very much appreciated, thank you.

First you want to reduce the brackets
Next you want to factor out the common number 3
Next you want to factor 20 + x^3 + 11x - 8x^2 by using the polynomial division method/technique
Lastly you just factor x^2 - 9x + 20 to get the answer.

Yes you are correct, the solutions are 1, 4, and 5.

Please help solve the following: 6(x-6)-5(x-7)=x+6

Digiron [165]

Answer:

$no \: solution$

Step-by-step explanation:

1) Expand

$6x - 36 - 5x + 35 = x + 6$

2) Simplify 6x - 36 - 5x + 35 to x - 1.

$x - 1 = x + 6$

3) Cancle x on both sides.

$- 1 = 6$

4) Since −1 = 6 is false, there is no solution.

No Solution

Hence, this equation have no solution.

Explain how you would choose a scale to use for a map. What things would you need to consider

lianna [129]

A scale drawing is an enlarged or reduced drawing of an object that is similar to an actual object. Maps and floor plans are smaller than the actual size. A scale drawing of a human cell is larger than the actual size.

On a map, the equal sign in 1 in. = 30 mi does not mean that the two quantities are equal, as it would in an equation.

A scale is the ratio that compares a length in a drawing to the corresponding length in the actual object. If a 30-mile road is 1 in. long on a map, you can write the scale of the map in these three ways:

13. For the arithmetic sequence: 6, 12, 18, 24,...

serg [7]

a_15 = 90

a_n = 6n

Step-by-step explanation:

Given sequence is:

6, 12, 18, 24,...

First of all we have to find the common difference. The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

$d=a_2-a_1 = 12-6 = 6\\d=a_3-a_2= 18-12 = 6$

The general form for arithmetic sequence is:

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

Putting the values for a_1 and d

$a_n=6+(n-1)(6)\\a_n=6+6n-6\\a_n=6n$

a) Find a15

$a_{15} = 6(15)\\=90$

b) Write an equation for the nth term.

The equation is: a_n=6n
