ANSWER
14x + 7y
EXPLANATION
We want to write the expanded form of the expression given:
7(2x + y)
To do this, we have to use the distribution property by using the number outside the bracket to multiply each of the terms in the bracket.
So, we have that:
7(2x + y) = (7 * 2x) + (7 * y)
= 14x + 7y
That is the answer.
A fair coin is tossed 3 times in succession. The set of equally likely outcomes is (HHH, HHT, HTH, THH, HTT, THT, TTH, TTT). Find the probability of getting a tailon the second toss
A fiar coin is tossed 3 times in succession.
The results for each experiment is displayed as follows;
[tex]\begin{gathered} \text{HHH} \\ \text{HHT} \\ \text{HTH} \\ \text{THH} \\ \text{HTT} \\ \text{THT} \\ \text{TTH} \\ \text{TTT} \end{gathered}[/tex]On each toss from the above results, the probability of getting a tail would include all results that has a tail come up. That would be;
[tex]P\lbrack\text{Event\rbrack}=\frac{\text{Number of required outcomes}}{Number\text{ of all possible outcomes}}[/tex][tex]P\lbrack\text{tail\rbrack}=\frac{4}{8}[/tex]Note that to get a tail on the "second toss" would mean to get a result with a tail as the second out of three. We have 7 outcomes with tails. However 4 of these has a tail as a second outcome, hence we have the required outcome as 4 out of a total of 8.

Ms. Wheeler asks her students to look at their desks. What do the desks represent inEuclidean geometry?
To determine the what desk represents in Euclidean geometry?
Euclidean geometry, sometimes called parabolic geometry, is a geometry that follows a set of propositions that are based on Euclid's five postulates
The most basic terms of geometry are a point, a line, and a plane. A point has no dimension (length or width), but it does have a location
In its rough outline, Euclidean geometry is the plane and solid geometry commonly taught in secondary schools
“A point is that which has no part” and “a line is a length without breadth.” Proceeding from these terms, he defined further ideas such as angles, circles, triangles, and various other polygons and figures.
For example, an angle was defined as the inclination of two straight lines, and a circle was a plane figure consisting of all points that have a fixed distance (radius) from a given centre.
Hence in Euclidean geometry the desk represent the plane
Does the set of ordered pairs {(-5, 0), (0, 1}, (5, 2), (10, 3), (15, 4)} represent a function? Why or why not?
Answer:
YES, it represents a function
Explanation:
For a relation to be a function, each member of the domain (input) must be matched to only one element in the range (output).
According to ordered pairs, we can see that the domain values are all unique as shown;
As you can see from the diagram, each input only has a unique corresponding co-domain (range). This shows that the ordered pairs represents a FUNCTION.

Mia was baking cupcakes for a party. She makes four drops of red food coloring for every six drops of yellow food coloring to dye her icing Orange. What is the ratio that would create the same orange color .
To find the ratio that would create the same orange color, we need to find the value from the division of the number of drops of each color of the food coloring.
From the present question, we know that Mia uses 4 drops of red for every 6 drops of yellow. It means that, for every 10 drops, 4 is red and 6 is yellow.
The ratio is:
( I will be finishing once I understand the best way to give you the final answer"
Each of these is a pair of equivalent ratios for each pair explain why they are equivalent ratios or draw a diagram that shows why they are equivalent ratios 2:7 and 10,000:35,000
Given this pair of equivalent ratios:
[tex]\begin{gathered} 2:7 \\ \\ 10,000:35,0000 \end{gathered}[/tex]It is important to remember that equivalent ratios represent the same value, but they have different forms.
Equivalent ratios can be obtained by multiplying both parts of a ratio by a common number.
In this case, you can identify that:
[tex]2\cdot5,000=10,000[/tex][tex]7\cdot5,000=35,000[/tex]Therefore, both parts of the original ratio can be multiplied by 5,000 in order to get the other ratio.
Hence, the answer is: They are equivalent ratios because they have the same value when they are simplified, and the second ratio can be obtained by multiplying both parts of the first ratio by 5,000.

original price of pants is 2995 the discount is 10%
Ok,
Since we have that the price of the pants is $2995 and that represents the 100%.
In order to determine the total value since we get a 10% discount, we do as follows:
[tex]2995\to100\text{ \& x}\to10[/tex]We determine the 10%, multiplying the percentage we want to know (10%) times the total ammount of money the pants cost ($2995) and then divide by the total percentage (100%):
[tex]x=\frac{2995\cdot10}{100}\Rightarrow x=299.5[/tex]x represents our 10% and so we extract x from the total:
[tex]T=2995-299.5\Rightarrow T=2695.5[/tex]Therefore the total price to pay is $2695.5
The vertices of a y rectangle are 8 A(1,7), B (3,7). C(3, 1.5), and 6 D (1, 1.5). Find the perimeter and the area of 3 the rectangle.
Let us first find the measures of the sides.
Width
We can find the width calculating the distance between points A and B. Doing so, we have:
The distance on the y-axis is 0 as they have the same coordinate
The distance on the x-axis is 2 ( x2 - x1= 3 - 1 = 2)
So, the width of the rectangle is 2.
Length
We can find the length calculating the distance between points B and C. Doing so, we have:
The distance on the x-axis is 0 as they have the same coordinate
The distance on the y-axis is 5.5 ( y2 - y1= 7 - 1.5 = 5.5)
So, the length of the rectangle is 5.5.
Using the formula for the perimeter, we have:
P= 2L + 2W (P:perimeter, l: length, w:width)
P= 2*(5.5) + 2*(2) (Replacing)
P= 11 + 4 (Multiplying)
P=15 (Adding)
The perimeter is 15
Using the formula for the area, we have:
A=l*w (A:area, l: length, w:width)
A=(2)*(5.5) (Replacing)
A= 11 (Multiplying)
The area is 11
