Answer:
-2(2x+3)
Step-by-step explanation:
Answer:
-2 (2x + 3)
Step-by-step explanation:
We need to use FOIL
Multiply the FIRST terms of each set together
Then the OUTSIDE terms
Then the INSIDE terms
and then the LAST terms
Thus:
[tex]2*2x = 4x[/tex]
[tex]2*3 = 6[/tex]
[tex]-4*3 = -12[/tex]
[tex]-4*2x = -8x[/tex]
So finally we end up with 4x + 6 - 12 - 8x
Simplifying this gives us -4x - 6
We can then factor out -2 from each factor, giving: -2(2x+3)
Hope this helps!

1. A circular running track is 1/4 mile long. Elena runs on this track, completing each lap in 1/20 of an hour. What is Elena's running speed, in miles per hour?
Answer: Elena's running speed = 5 miles per hour.
Step-by-step explanation:
Length of track = [tex]\dfrac14 \text{ mile}[/tex]
Time taken to complete one lap = [tex]\dfrac{1}{20}[/tex] of an hour.
Elena's running speed = [tex]\dfrac{Distance}{Time}[/tex]
[tex]=\dfrac{\dfrac14}{\dfrac1{20}}\text{ miles per hour}\\\\=\dfrac{20}{4}\text{ miles per hour}\\\\=5\text{ miles per hour}[/tex]
Hence, Elena's running speed = 5 miles per hour.

What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
In the figure ABCD, is transformed to figure A'B'C'D'.
A figure will be mapped onto itself if it circles the graph 360 degrees.
As there are 360 degrees in a circle, the figure has just completed a full circle and returned to where it was before rotating.

Answer:
c =2
Step-by-step explanation:
2(6c+2)+3c=2 (19 -c)
1. Distribute
2(6c +2 ) + 3c = 2 ( 19 - C )
12c + 4 +3c = 2 (19 - C )
2. Combine like terms
12c + 4 + 3c = 2 ( 19 - c )
15c + 4 = 2 (19 - c )
3. Rearrange terms
15c + 4 = 2( 19 - C )
15c + 4 = 2 ( -c + 19 )
4. Distribute
15c + 4 = 2 ( -c + 19 )
15c + 4 = -2c + 38
5. Subtract 4 from both sides of the equation
15c + 4 = -2c + 38
15c + 4 -4 = -2c + 38 -4
6. Simplify
Subtract the numbers
Subtract the numbers
15c = -2c +34
7. Add 2c to both sides of the equation
15c = -2 +32
15c +2c = -2c + 34 + 2c
8. Simplify
Combine like terms
Combine like terms
17c = 34
9.Divide both sides of the equation by the same term
17c = 34
17c/17 = 34/17
10. Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
c = 2

A store is going out of business. Everything is marked down 40%. How much do you pay now for an item that used to cost $150? Explain how you got your answer.
Answer:
You would pay $90 now for an item that used to cost $150.
Step-by-step explanation:
Here's how I thought of it. There are two ways to solve this problem.
Because we know that the item is discounted by 40%, that leaves 60% of its price left. (100% price - 40% price = 60% price).
Thus, you would multiply $150 by 0.6 (or, 60% in decimal form), which equals $90.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alternatively, you could also multiply $150 by 0.4 and just subtract what you get from the total. That number is 60, and $150 - $60 = $90.
Use whichever way makes more sense to you!
