( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )
Step-by-step explanation:
[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5
(Multiply 3 from [tex]3x^{2}[/tex] with -5)
Product = -15
Sum = -2
(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)
[tex]3x^{2}[/tex] + 3[tex]x[/tex] - 5
3[tex]x[/tex] ( [tex]x[/tex] + 1 ) - 5 ( [tex]x[/tex] + 1 )
= ( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )
Why is subtracting an expression similar to distributing a –1?
You increase each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.
You multiply each term inside the parentheses by –1 in order to add each term, since subtraction is the multiplicative inverse.

Answers
Using the distributive property, distributing -1 ; multiplies each term in the parenthesis by a negative sign. Hence, it is similar to subtraction because You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.
The additive inverse of a value is the value which ensures that the addition of two values gives 0.
Using the relation :
(w + x) - (y + z)
The negative sign implies distributing -1 to all values in the parenthesis ;
w + x - y - z
Hence, it is similar to using the subtraction operation directly :
(w + x) - y - z
Therefore, subtraction ls similar to distributing - 1

Step-by-step explanation:
Problem One
Perimeter is in meters not square meters. The equation is
2*(6.8+x) + 2*12.5= 47 Remove the brackets. Combine like terms
13.6 + 2x + 25 = 47
38.6 + 2x = 47 Subtract 38.5 from both sides
2x = 47 - 38.6
2x = 8.4 Divide by 2
x = 4.2
Answer D
Problem 2
This problem is asking that you calculate the perimeter of a swimming pool.
The two semicircles on the ends make a whole circle.
The diameter of the semicircles is obtained from the difference of the two given lengths.
The rectangle has a length of 12. The length of the rectangle and the 2 semicircles is 16. The difference is 4. You could divide this by 2 to get the radius. I would just leave it as the diameter.
So the perimeter is pi*d + 2 * 12 [there are 2 lengths]
Perimeter = 4*pi + 24
Perimeter = 12.56 + 24
Perimeter = 36.56
Answer A
Problem 3
This is the circle inside the square.
The radius of the circle = 9
The diameter of the circle and the length of square's side = 2*9 = 18
The area of the square = s^2 where s = 18
The area of the square = 18^2 = 324
The area of the circle = pi * 9^2 = 3.24 * 81 = 251.34
The area of the Shaded area = 324 - 251.34 = 69.66
Answer C
Problem 4
b1 = 5
b2 = 11.5
h = 4.5
Formula
Area = (b1 + b2 ) * 4.5/2
Area = (5 + 11.5) * 4.5 /2
Area = 16.5 * 4.5 / 2
Area = 74.25/2
Area = 37.125

Aliyah bought a car for $32,000. It is now worth $5000 less than half of what she purchased it for. To the nearest tenth of a percent , find the percent decrease in the value of the car.
Answers
16000- 5000 = 11000
11000 / 32000= 0.34375
1- 0.344= 0.656
Answer : D
The percent decrease in the value of the car is 65.6%.
Given that,
The purchase value of the car is $32,000.
The worth of the car is now $5,000 that should be lower than the half of purchased value i.e.
= 50% of $32,000 - $5,000
= $16,000 - $5,000
= $11,000
Now the percentage of decrease in the value of the car is
[tex]= \frac {(\$32,000 - \$11,000)}{\$32,000} \\\\= \frac{\$21,000}{\$32,000}[/tex]
= 65.6%
Therefore we can conclude that the percentage of decrease in the value of the car is 65.6%.
Therefore, all the other options are incorrect.

Robert is an avid runner who as a specific route he runs each morning. He leaves his house and runs 3
miles north before stopping for a 1 minute break. After his break he runs 4 miles east before taking a 2
minute break. Next he runs 5 miles southwest back to his home. What is his average speed if the route
without the breaks takes 57 minutes to complete?
Answers
Answer:
he's running 4/19 miles per minute or 12.6 miles per hour
Step-by-step explanation:
he is running 3 miles north, 4 miles east, and 5 miles southwest, a total of 12 miles
d = rt
12 = 57r
r = 12/57 or 4/19 (simplest form)
this is 4/19 miles per minute, multiply by 60 and it's about 12.6 miles per hour

The restaurant manager suggests that they order one pizza for every 6 people. How many pizzas
should they order?
Answers
First, add up the numbers of players on each team and the coachesto get the total number of people eating.
17 + 21 + 20 + 17 + 9 = 84
Then, you can divide 84 by 6 to see how many pizzas: 84/6 = 14
If you’re teacher wants you to set it up as a ratio, it’s 6/1 = 84/x
Then you cross-multiply:
6x = 84
Divide both sides by 6
x = 14

The temperate in Anchorage, Alaska at 9am was at -2°F. At 9pm the temperature decreased 7°F. Write an expression that represents the difference between the temperature from 9am to the resulting temperature at 9pm. How do I write the expression?
Answers
Im calling temperature T and time t for our equation but they can just as easily be Y and X
In 12 hours time the temp decreased 7 degrees so to get the slope we went down 7 and over 12 making it -7/12 (since we went down)
The at the starting point of t=0 it’s already -2 F making that our “y intercept” T intercept in this case
y=mx +b
In our case y=T x=t m=-7/12 and b= -2
Replace them to get
T=(-7/12)t-2
