1) Examining that picture, we can state the following about that:
The shaded triangles area:
[tex]\frac{1}{2}ab\text{ +}\frac{1}{2}ab+\frac{1}{2}ab+\frac{1}{2}ab=2ab[/tex]Note that the area of the triangle is 1/2 the product of the base by its height.
The area of that white inner square is given by c² since the Area of a square is equal to the side length raised to the 2nd powe.
2) Then
The expression 2ab + c² represents the area...
The equivalent expressions (a+b)² and a² + 2ab + b² use the length of the figure (a square) raised to the 2nd power. As explained above.
For the last statement let's calculate it:

A customer at a shipping store is planning to send a package and is considering two options. The customer can send a package for $3, plus an additional $2 per pound. The cost, y, can be represented by the equation y = 3 + 2x, where x represents the amount of pounds of the package. Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
Based on the graph of the system of equations, when will the cost of the two shipping options be the same?
A package that weighs 10 pounds will cost $17 for both options.
A package that weighs 7 pounds will cost $17 for both options.
A package that weighs 17 pounds will cost $31 for both options.

What is an equation?A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
The cost, y, can be represented by the equation: y = 3 + 2x,
x = the amount of pounds of the package
Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
The equation will be equated together.This will be:
3 + 2x = 17
Collect like terms
2x = 17 - 3

Hank has just purchased a small rectangular fish tank that holds 950.4 milliliters of water. The tank has a width of 8.8 cm and a height of 9 cm. what is the length of the fish tank?
Answers
We will investigate how to determine one of the indicator dimensions of a regular figure.
We have a rectangular fish tank which can be modeled as a cuboid. The indicator lengths of a cuboid or a rectangular fish tank are as such:
[tex]\begin{gathered} \text{Length ( L ) } \\ \text{Width ( w ) = 8.8 cm} \\ \text{Height ( h ) = 9 cm} \end{gathered}[/tex]One of the indicator lengths of the rectangular fish tank Length ( L ) is unknown. Howver, we are given the total amount of water that the fish tank can withold as follows:
[tex]\text{Water in fish tank = 950.4 mL}[/tex]We will use the conversion factor between milliLiters and centimeter cube as follows:
[tex]1\text{ mL }\to1cm^3[/tex]Therefore,
[tex]950.4\text{ mL }\to950.4cm^3[/tex]The amount of water a fish tank can hold is equivalent to the volume of the fish tank. We have modeled our rectangular fish tank as a cuboid. The volume ( V ) of a cuboid can be expressed in terms of its indicator dimensions as follows:
[tex]V\text{ = L}\cdot w\cdot h[/tex]We can use the above volume expression to determine one off our missing indicator dimension of length ( L ). We plug in the respective quantities and evaluate:
[tex]\begin{gathered} 950.4\text{ = L}\cdot(8.8\text{ ) }\cdot\text{ ( 9 )} \\ \\ L\text{ = }\frac{950.4}{8.8\cdot9}\text{ = }\frac{950.4}{79.2} \\ \\ L\text{ = 12 cm} \end{gathered}[/tex]Therefore, the length ( L ) of the fish tank must be:
[tex]12\text{ cm }\ldots\text{ Answer}[/tex]Abdul, Beckie, Cynthia and Douglas are making pancakes according to the recipe below:Which person can make the most pancakes?BeckieAbdulCynthiaDouglas
Answers
To make 12 pancakes we need 100 g flour, 2 eggs, 300 ml milk
Abdul has 175 g flour, 4 eggs and 500 g milk
The ration between Abdul's amount of each ingredient and the total needed to make 12 pancakes is: (175/100) = 1.75 flour, (4/2) = 2 eggs, (500/300) = 1.67 milk.
So, the total amount of pancakes that Abdul can make is determined by the amount of the less abundant ingredient (milk): 1.67*12 = 20 pancakes
Doing the same steps for Beckie, we got that her less abundant ingredient is milk, with a ratio of 400/300 = 1.33. Then, she can make 1.33*12 = 16 pancakes.
For Cynthia, her less abundant ingredient is flour, with a ratio of 150/100 1.5. Then, she can make 1.5*12 = 18 pancakes.
And for Douglas, his less avundant ingredient is egg, with a ratio of 3/2 = 1.5. Then, he can make 1.,5*12 = 18 pancakes.
Therefore, Abdul is the one who can make the most pancakes

What is the Composition of Functions?The composition of the functions f(x) and g(x), where g(x) acts first, is denoted by f(g(x)) or (fog)(x). A new function is created by combining two or more existing functions. The output of the function inside the parenthesis that is being composed becomes the input for the function outside of the parenthesis. i.e.,In f(g(x)), g(x) is the input to f(x).In g(f(x)), f(x) is the input to g(x).Given the composition of functions g(f(x)),
For which f(x) = x + 5, and g(x) = x² - 4x + 8.
Considering f(x) as input we substitute it in g(x) in place of x.

The mean of 6 numbers is 12.
The numbers are in the ratio 1 : 1 : 1 : 1 : 2 : 3.
Find the range.
Answers
Answer:
range = 16
Step-by-step explanation:
The total of all the numbers = mean x number of values = 6 x 12 = 72
The ratio of the numbers is
1: 1: 1: 1:2 :3
The sum of the ratios is 9
So the numbers in the ratio of 1 must be 1/9 x 72 = 8
The number with a ratio of 2 must be 2 x 8 = 16

The range of the numbers is 24-8 = 16

The sphere at the right fits snugly inside a cube with 4-in. edges. What is the approximate volume of the space between the sphere and cube?
Answers
As given by the question
There are given that the inside edge is 4 in.
Now,
Since sphere fits snugly inside a cube therefore diameter of sphere will be equal to side of the cube
So,
[tex]\begin{gathered} \text{diameter}=4\text{ inches} \\ \text{radius}=\frac{dameter}{2} \\ \text{radius}=\frac{4}{2} \\ \text{radius}=2 \end{gathered}[/tex]Then,
Volume of the sphere is given by:
[tex]\begin{gathered} \frac{4}{3}\times\pi\times r^3=\frac{4}{3}\times3.14\times2^3 \\ =\frac{4}{3}\times3.14\times8 \\ =33.5 \end{gathered}[/tex]And,
The volume of a cube is:
[tex]\begin{gathered} \text{Volume of cube=side}\times side\times side \\ =4\times4\times4 \\ =64\text{ inches} \end{gathered}[/tex]Then,
The volume of the space between the sphere and cube = 64-33.5 = 30.5.
Hence, the answer is 30.5 cube inches.

For f(x) = 2x + 12 and g(x) = 2x² + 2x + 12 the value of (g o f)(-8) is 36.
Solution:Given that f(x) = 2x + 12, g(x) = 2x² + 2x + 12.
to locate (g o f) (-8),
To find (g o f)(-8), we must first find g(f(x)) and then substitute x = -8.
Find g(f(x)) by substituting f(x) into g. (x)
= g(f(x)) = 2( 2x +12)² + 2( 2x + 12) + 12
x = -8 so,
g( f( - 8) ) = 2( 2(-8) +12)² + 2( 2(-8) + 12) + 12
g( f( - 8) ) = 2( -16 +12)² + 2( -16 + 12) + 12
g( f( - 8) ) = 2(-4)² + 2( -4 ) + 12
g( f( - 8) ) = 2 x 16 -8 + 12
g( f( - 8) ) = 32 - 8 + 12
g( f( - 8) ) = 36

What is Algebra?
One of the many different mathematical disciplines is algebra. Algebra, a common thread that runs through nearly all of mathematics, is the study of mathematical symbols and the rules for using them in formulas.
To feed his plants, Miguel combines water and plant food. According to the directions on the plant food, you should add 1 teaspoon to every 4 cups of water. To demonstrate the relationship between cups of water (w) and teaspoons of plant food (f), create an equation.
48 teaspoons = 1 cup.
1 teaspoon = plants food
4 cups = water.
= 48 teaspoons x 4.
= 192 teaspoons
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
The mixture = 192w + f
The relation between f and w is f = kw.
1 teaspoon = plant food
7 cups = water.
= 48teaspoon x 7
= 336teaspoon
The formula is:
water in cups = w
Teaspoon of nourishment for plants equals f
