Step-by-step explanation:
In order to properly distribute, multiply the number on the outside of the parenthesis by the numbers on the inside.
Here is an example:
[tex]8 (5+8)[/tex]
[tex]8*5=40.[/tex]
[tex]8*8=64.[/tex]
This simplifies to:
[tex]8(5+8)=40+64..[/tex]
The Distributive Property is quite simple.
The Distributive Property tells us how we can solve expressions in the following form:
a(b+c)
The distributive property is sometimes called the distributive law of multiplication and division.
Let me lay out an example to help you understand this property.
When we see an expression such as 2(4+3), we typically think to solve it like so:
2(4+3)
2(7)
14
This is called using the order of operations (PEDMAS, or whatever you call it.)
With the distributive property or distributive law of multiplication and division, you would instead multiply the '2' by every number in the brackets. This would look like
2(4+3)
2(4)+2(3)
8+6
14
We are distributing the 2 to the 4 and then to the 3.
Just remember, when you use the distributive property, you must always multiply the number outside of the bracket by every number inside the bracket.
Here are some examples for you to try:
4(8+2)
7(2+4)
Answers:
4(8+2)
4(8)+4(2)
32+8
40
7(2+4)

Solving Quadratic Equations-factoring
How do find what b could be? My book says to factor completely.
3b²+15b+12=0
Answer:
b = −1
b = −4
Step-by-step explanation:
Common Factor
Divide both sides of the equation by the same term
Use the quadratic formula
Answer:
-1 or -4
Step-by-step explanation:
first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b
doing this, we would have our two numbers to be
12b and 3b
replace these two numbers with 15b in the equation
3b² + 12b + 3b + 12=0
(3b²+12b) + (3b+12)=0
3b(b+4)+3(b+4)=0
note: the numbers in the brackets must be the same
(3b+3)(b+4)=0
therefore, 3b + 3= 0 or b + 4= 0
3b+3= 0
3b=-3
b=-3/3
b=-1
or
b+4=0
b=-4

How do you solve this?
Answer:
C.)
Step-by-step explanation:
The graph is positive this time, so right away you can eliminate A and B.
If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.
Answer: C: 1/2
Step-by-step explanation:
Rise over run tells us that this graph is going up 1 and right 2. Since it’s going up and right it’s going to be positive and since we do rise over run on our slope fraction, that leaves us with C, 1/2.

Lauren opened a lemonade stand on her street. It costs her $8.00 to buy the supplies each day, and she sells lemonade for $2.50 a cup. If she wants to make at least $175.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Lauren needs to sell? Input your answer as a whole number.
Picture added
Answer:
180.5 cups
Step-by-step explanation:
profit is 175, she spends $8 on supplies each day. 8+175= 183. 183 is what she initially made each day. 183 divided by 2.5= 180.5

The local restaurant has the following offers:
2 sandwiches and juice
€5.00
OFFER A
Sandwich and salad
€5.10
OFFER B
Salad and juice
€5.30
OFFER C
What is the cost of one sandwich?
What is the cost of 1 sandwich 1 salad and 1 juice?
Answer:
Below in bold.
Step-by-step explanation:
Let cost of sandwich = s, juice = j and salad = d.
2s + j = 500 (A)
s + d = 510 (B)
d + j = 530 (C)
Equation (C) - (B) ( to eliminate d):
j - s = 20 (D)
(A) - (D) = (to eliminate j):
2s - (-s) = 480
3s = 480
s = 160
A sandwich costs E 1.60.

Select the equations corresponding to d, the distance between points (2, -6) and (2, 5).
a) d = |-6| – |5|
b) d = |2| – |2|
c) d = |5| – |-6|
d) d = |5| + |-6|
e) d = |2| + |2|
f) d = |-6| + |5|
The distance between points (2, -6) and (2, 5) is d = |-6| + |5|.
In the first step, we plot the two points. Then, connect the two points. Count the distance between Quadrant I and Quadrant IV.
Quadrant I contains 5 units and quadrant IV contains 6 units. We know that the vertical line denotes the y-value. Therefore, we take the Quadrant IV value as -6.
Since, we use the determinant sign the result will be d = |-6| + |5|.
To find the distance between two points:

Use the permutation formula to solve a problem when n = 15 and r = 4.
A.
B. 54
C. 3,276
D. 32,760
[tex]nPr = \frac{n!}{(n - r)!} [/tex]
[tex]15P4 = \frac{15!}{(15 - 4)!} = \frac{15!}{11!} \\ = \frac{15 \times 14 \times 13 \times 12 \times 11!}{11!} \\ 15 \times 14 \times 13 \times 12 = 32760[/tex]
The permutation of the given values will be [tex]32,760[/tex].
What is permutation ?A permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters.
Permutation [tex]^nP_{r}= \frac{n!}{(n-r)!}[/tex]
We have,
[tex]n = 15[/tex]
And
[tex]r = 4[/tex]
So, using Permutation Formula;
Permutation [tex]^nP_{r}= \frac{n!}{(n-r)!}[/tex]
i.e.
[tex]^nP_{r}= \frac{15!}{(15-4)!}[/tex]
[tex]= \frac{15!}{11!}= \frac{15*14*13*12*11!}{11!}[/tex]
Now, cancelling factorial terms,
We get,
[tex]^nP_{r}= 15*14*13*12[/tex]
[tex]^nP_{r} =32760[/tex]
So, the value is [tex]32760[/tex].
Hence, we can say that the permutation of the given values will be [tex]32,760[/tex].
