The product of the given expressions will be 84x¹²
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 4x(-3x⁸)(-7x³) we need to find the product of the same,
So, the product is =
4x(-3x⁸)(-7x³)
= 4x × (-3x⁸) × (-7x³)
= 4 · x · (-3) · x⁸ · (-7) · x³
= 4·21·x⁽¹⁺⁸⁺³⁾
= 84x¹²
Hence, the product of the given expressions will be 84x¹²

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?
1st container: witdh9.33cm Lenght 3.2cm
2nd container: witdh 20.5cm lenght 6.5cm and on the side 3.25cm
The cylinder has a........A)Smaller surface area B)bigger C)equal
And will cost.....A)Less to produce B)more C)The same
Answer:
a) 2nd container is more efficient and contains the elements for a container.
b) The cylinder has a........A)Smaller surface area B)bigger C)equal
And will cost.....A)Less to produce B)more C)The same
Step-by-step explanation:
a) The 2nd container has these elements:
Width 20.5cm
Length 6.5cm
side 3.25cm
So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.
This container can hold the 300cm3 of juice.
b) A cylinder is a geometric solid common in everyday life. Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders. The two ends are called bases, and are usually circular. Though, they can take other shapes. When a cylinder is unrolled and flattened out, the side is actually a rectangle.
The surface area of a cylinder is the surface area of each end plus the surface area of the side. The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

Part 1:"The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet tall and 4 feet wide. They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot.
Do they have enough money to cover the cost of making the window?" (PART 1 IS DONE)
Part 2:"A local community member sees the school’s stained glass window and really likes the design. They ask the students to create a larger copy of the window using a scale factor of 3 (9 feet tall and 12 feet wide). Would $450 be enough to buy the materials for the larger window?"

Find the sum of the numbers as a product of their GCF is 84 + 108
Hey there! :)
I believe the correct answer to your question is 12.
Find the prime factorization of 84
84 = 2 × 2 × 3 × 7
Find the prime factorization of 108
108 = 2 × 2 × 3 × 3 × 3
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 2 × 3
GCF = 12

1) Tanya is buying edging for a triangular flower garden she plans to build in her backyard. If the lengths of the three pieces of edging that she purchases are 13 feet, 10 feet, and 7 feet, will the flower garden be in the shape of a right triangle ?
Answer:
The Flower Garden is not in the shape of a right Δ
Step-by-step explanation:
~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~
Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;
a^2 + b^2 = c^2,
10^2 + 7^2 = 13^2,
100 + 49 = 169,
149 ≠ 169,
So the Flower Garden will not be in the shape of a right Δ
Write an equation of the line in slope-intercept form. The points are (0,1) and (2,-5)
Your answer is y = -3x + 1
To find the equation of the line we need both the slope and where it intercepts the y-axis. We are given where it intercepts the y-axis because they tell us it goes through the point (0, 1) and this is a point where x = 0, so it must be on the y-axis.
The equation for finding the slope of a line given two points is [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are points on the line. Using this, we can substitute in the points we're given and get:
(-5 - 1)/(2 - 0) = -6/2 = -3
Therefore our slope is -3 and our intercept is 1, so the final answer is y = -3x + 1

Answer: [tex]5x\sqrt{3x}[/tex]
Step-by-step explanation:
The factors of 75 are 5, 5, and 3. Since there are two 5's, we can take the square root of them to get 5. x^3 has x, x, and x. There are also two x's, which means that we can square root them to equal just x.
The graph of f(x) = |x| is vertically stretched by a factor of 3, shifted left 2 units, shifted down 4 units and reflected over the x-axis. What is the function equation of the resulting graph?
Answer:
The final transformed function becomes:
[tex]f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
The first transformation (vertically stretched by a factor of 3) means we multiply by 3 the original function:
[tex]f(x)= 3\,|x|[/tex]
second transformation (shifted left 2 units) means we add 2 units to "x":
[tex]f(x)=3\,|x+2|[/tex]
third transformation (shifted down 4 units) implies that we subtract 4 units to the full functional expression:
[tex]f(x)=3\,|x+2|-4[/tex]
fourth transformation (reflected over the x-axis) implies that we multiply the full functional expression by "-1":
[tex]f(x)=(-1)\,(3\,|x+2|-4)\\f(x)=-3\,|x-2|+4[/tex]
Step-by-step explanation:
Step 1: Add the vertical stretch
[tex]f(x) = |x|[/tex]
[tex]f(x) = 3|x|[/tex]
Step 2: Shift it to the left 2 units
[tex]f(x) = 3|x|[/tex]
[tex]f(x) = 3|x + 2|[/tex]
Step 3: Shift it down 4 units
[tex]f(x) = 3|x + 2|[/tex]
[tex]f(x) = 3|x + 2| - 4[/tex]
Step 4: Reflect it across the x-axis
[tex]f(x) = 3|x + 2| - 4[/tex]
[tex]f(x) = -3|x + 2| - 4[/tex]
Answer: [tex]f(x) = -3|x + 2| - 4[/tex]

Answer:The area is 14306. 625 cm.
Step-by-step explanation:
To find the area of the circle, we will need to find the diameter and find the radius.
So we know the circumference is 423.9 m and we know to get the circumference, you will need to multiply pie by the diameter .
so now we need divide the circumference by pie to find the diameter.
423.9/ 3.14 = 135 so 135 is the diameter.
To find the radius we need to divide the diameter by 2.
135/2 = 67.5
Now is time to find the area which uses the formula A= nr^2
A = 3.14 * 67.5^2
A = 14306. 625

What is the circumference, in centimeters, of the circle? Use 3.14 for n. Enter your answer in the box
Answer:
75.36
Step-by-step explanation:
The circumference of a circle is just the diameter, 24 in this question times 3.14.
The solution is, 75.36 cm is the circumference, in centimeters, of the circle.
What is perimeter?A perimeter can be mentioned as a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
Perimeter means to the total outside length of an object,
here, we have,
the diameter, 24 cm (in this question)
now, we have to find the circumference,
we know that,
The circumference of a circle is the diameter times 3.14.
so, we get,
the circumference = 24*3.14 cm
=75.36cm
Hence, The solution is, 75.36 cm is the circumference, in centimeters, of the circle.

Marissa jumped 42 times in 7 hours. At that rate, how many times would she jump in 30 minutes?
Answer:
3
Step-by-step explanation:
Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

A sector with a radius of 15 cm has a central angle measure of 8pie/5
What is the area of the sector?
Answer:
The area of the sector is [tex]180\pi \ cm^2[/tex].
Step-by-step explanation:
We have,
Radius of circle is 15 cm
Central angle is [tex]\dfrac{8\pi}{5}\ \text{radian}[/tex]
It is required to find the area of the sector. The formula used to find the area of sector is given by :
[tex]A=\dfrac{1}{2}r^2\theta[/tex]
Plugging all the values in above formula as :
[tex]A=\dfrac{1}{2}\times 15^2\times \dfrac{8\pi}{5}\\A=180\pi \ cm^2[/tex]
So, the area of the sector is [tex]180\pi \ cm^2[/tex].
