Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
2(3x + 1)(x + 1)
Step-by-step explanation:
Given
6x² + 8x + 2 ← factor out 2 from each term
= 2(3x² + 4x + 1) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × 1 = 3 and sum = 4
The factors are + 3 and + 1
Use these factors to split the x- term
3x² + 3x + x + 1 ( factor the first/second and third/fourth terms )
= 3x(x + 1) + 1(x + 1) ← factor out (x + 1) from each term
= (3x + 1)(x + 1) , then
3x² + 4x + 1 = (3x + 1)(x + 1)
and
6x² + 8x + 2 = 2(3x + 1)(x + 1) ← in factored form
0.2(k + 2.4) = 3.2k. Please help me.
Answer:
k = 0.16
Step-by-step explanation:
First, use distributive property on the left side:
[tex]0.2(k+2.4)=3.2k\\0.2k+0.48=3.2k\\0.48 = 3k\\k = 0.16[/tex]
Answer:
k = 0.16
Step-by-step explanation:
Use distributive property, meaning individually multiply 0.2 to each number/variable within the parameters
0.2 × k = 0.2k
0.2 × 2.4 = 0.48
0.2k + 0.48 = 3.2k
You cannot add a number and a variable so instead we should isolate the variable
Subtract 0.2k from both sides
0.48 = 3.2k - 0.2k
0.48 = 3.0k
0.48 = 3k
Divide both sides by 3
0.16 = k

14 Customers into the store over the course of seven minutes how many Internet store after one minute
Answer:
2
Step-by-step explanation:
14 divided by 7 is two customers in one minute
Answer:
After one minute there will be 2 people inside the store.
Step-by-step explanation:
First we put this into a proportion. Aka set up like a fraction.
14 (customers) x
------- ---> ------
7 (minute) 1 minute
In order to find x, we must divide by 7 because in order to make the bottom number one on the bottom, you must divide by 7 , so we do the same to the top.
14/7 is 2.
This means that per minute, there are 2 people inside the store.
After one minute, There will be 2 people inside the store.

Answer:
The answer is
[tex]a = 9 \sqrt{3} \: and \: b = 9[/tex]
Answer:
B
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , cos60° = [tex]\frac{1}{2}[/tex]
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{18}[/tex] ( multiply both sides by 18 )
18 × sin60° = a , then
a = 18 × [tex]\frac{\sqrt{3} }{2}[/tex] = 9[tex]\sqrt{3}[/tex]
-------------------------------
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b}{18}[/tex] ( multiply both sides by 18 )
18 × cos60° = b , then
b = 18 × [tex]\frac{1}{2}[/tex] = 9

Pepper has 7.5 bags to clear 12 yd squared to distribute evenly among the beds . About how many bags will she need to use for each square yard?
Answer:
5/8 bags
Step-by-step explanation:
Pepper ha 7.5 bags
These bags are needed to clear 12 yards squared equally
Therefore the number of bags required for each square yard can be calculated as follows
= 7.5/12
= 0.625
0.625 to fraction is 5/8
Hence 5/8 bags is needed for each square yard

Find the measure of each angle in the angle pair described.
The measure of one angle is twice the measure of its supplement. What are the measures of the two angles?
Answer:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree

Add your sales tax with the original cost, now you have the final total
what does this equal y=8x+1
y=6x+3
Answer:
(1,9)
Step-by-step explanation:
Step 1: Understand what the question is asking you
Assuming the question is asking you to solve for the point of interesection of the linear system
Step 2: Solve
Equate the 2 linear equations to each other and solve for'x'
8x + 1 = 6x + 3
8x - 6x = 3 - 1
2x = 2
[tex]\frac{2x}{2} =\frac{2}{2}[/tex]
x = 1
Sub x = 1 into any of the 2 equation for y
y=8(1)+1
y=8 + 1
y=9
Step 3: Therefore Statement
Therefore the answer to the linear system is (1,9)
The point of intersection for the two equations is (x=1, y=9).
To find the point where the two equations intersect, we can set them equal to each other since they both represent "y." So, we have:
8x + 1 = 6x + 3
Now, let's solve for "x":
8x - 6x = 3 - 1
2x = 2
x = 2/2
x = 1
Now that we have the value of "x," we can find the corresponding value of "y" by substituting "x = 1" into either equation. Let's use the second equation:
y = 6x + 3
y = 6(1) + 3
y = 6 + 3
y = 9
So, the point of intersection for the two equations is (x=1, y=9).

The population of Williston is currently 21,200 people. If the population
increases at an average rate of 415 people per year, which equation could
be used to find the approximate number of years it will take for the
