2(6x + 6) is 12x + 12
16x - 8 is 8(2x - 1)
3(x - 2) is 3x - 6
3(4x + 4) is 12x + 12
2x + 6 is 2(x + 3)
4(x + 3) is 12x + 12
Step-by-step explanation:
Distribute the number in front of the parenthesis to the numbers inside the parenthesis .
for example: 3(x-2)
3 times x = 3x
3 times -2= -6
answer: 3x - 6

Answer:
8 and 64
Step-by-step explanation:
4/1 = 4
8/2 = 4
32/8 = 4
64/16 = 4
Answer:
1:4
2:8
8:32
16:64
Step-by-step explanation:
The constant of proportionality is 1:4. Whatever number is on the right has to be 4 times greater than the number on the left for it to be proportional. I divided 32 by 4 to get 8 on the first one, and I multiplied 16 by 4 on the second one to get 64.
Hope this helps!

Jenna can swim 150 meters in 3 minutes. If you graph this with minutes on the X-axis and meters on the Y-axis, what will be the slope of the line? Which of the following are increased in concentration in a basic solution
The equation of a line is y = 50x. Then the slope of the line is 50 meters per minute.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
Jenna can swim 150 meters in 3 minutes.
If you graph this with minutes on the X-axis and meters on the Y-axis.
Then the slope of the line will be

m = 50 mters per minute
Then the equation will be
y = 50x

Answer:
63 houses have been sold this year.
Step-by-step explanation:
There are 81 houses in the community. If 7/9 are sold this year, then all you have to do is multiplication.
In this case, you would multiply 81 by 7/9 to get your answer.
81/1 x 7/9:
Cancel out the 9 and the 81. Then the denominator will be 1 x 1 and the numerator would be 7 x 9. It would be 63 (7x9=63) over 1 (1x1=1) which is just 63. Make sure to include units.

Write inequalities to represent the situations below.
The vehicle's fuel efficiency is no less than 45 miles per gallon.
Use f to represent the vehicle's fuel efficiency (in miles per gallon).
Martina exercises at least 45 minutes per day.
Use t to represent Martina's amount of exercise (in minutes per day).
Answer:
[tex]f \ge 45[/tex]
[tex]t \ge 45[/tex]
Step-by-step explanation:
Solving (a): No less than 45
In inequalities, no less than means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]f \ge 45[/tex]
Solving (b): At least 45
In inequalities, at least means [tex]\ge[/tex]
So, the statement can be represented as:

Ms. Gartland bought x number of shirts for the new members of her chorus. The cost for x number of shirts including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on the purchase. What equation could be used to find x.
A - 3.99(x + 12.25) = 77.49
B - 3.99x + 12.25 = 77.49
C - 12.25(x + 3.99) = 77.49
D - 12.25x + 3.99 = 77.49
Answer: The answer would be
D - 12.25x + 3.99 = 77.49
Step-by-step explanation:
If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.
