The Coefficient of x² in the equation (3x²-5)(4+4x²) after simplification is -8 .
The Equation is given as : (3x²-5)(4+4x²)
To simplify , we first multiply the terms inside the bracket ;
So , given equation can be written as (3x²-5)×(4+4x²)
⇒ 12x² + 12x⁴ - 20 - 20x²
Adding the like terms of the equation ,
we get ;
⇒ (12 - 20)x² + 12x⁴ - 20
Simplifying further , we get
⇒ 12x⁴ - 8x² - 20 .
In the equation above we see that the numerical term with the x² is (-8) .
Therefore , the required coefficient is -8 .

Answer:
16
Step-by-step explanation:
Answer:
4 and -4
Step-by-step explanation:
To solve, just isolate x
2+x^2=18
subtract both sides of the equation by 2
x^2=16
find the square root of 16
(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)

Answer:
5n + 5a
Step-by-step explanation:
This would be your simplified algebra expression.
Answer:
The distributive property tells us how to solve equations in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. Normally when we see an equation like this … 4(8+3) distributive property format 4(8+3) -> 4(11) -> 44 we just evaluate what’s in the parentheses first, then solve it: 4(8+3)=4x8 + 4x3=44 These are the 2 methods

A woodworker wants to cut a board that is 10.016 feet long into 4 equal-length pieces. How long will each of the cut boards be?
Answer:
2.504 feet
Step-by-step explanation:
Find the length by dividing 10.016 by 4
10.016/4
= 2.504
So, each cut board will be 2.504 feet
We have
[tex] \begin{cases} \sf No. \: of \: pieces = \frak{4} \\ \sf Total \: Length = \frak{10.016 \: ft} \end{cases} [/tex]
So,
Length of 1 board = 10.016/4
Length of 1 board = 2.504 ft
So,
The length of 1 board is 2.504 ft.
Describe how you know that (8+9)+3 is equivalent to 8+(9+3). What is the benefit to using this property
Answer:
Associative property of addition
Step-by-step explanation:
The associative property of addition is as follows :
a+(b+c) = (a+b)+c
We have,
a = 8, b = 9 and c = 3
So,
Using above property,
(8+9)+3 = 8+(9+3)
20 = 20

A ringtoss toy is composed of a rectangular prism on top of a cylinder. The rectangular prism is completely filled with water. The dimensions of the rectangular prism are shown in the diagram.
What is the volume of the rectangular prism in cubic centimeters?
165 cm3
270 cm3
348 cm3
26 cm3
Answer:
270 cm3
Step-by-step explanation:
The volume of the given rectangular prism is 270 cm³.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.
Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have
Length = 9 cm
Width = 2 cm
Height = 15 cm
Using the formula for volume of the rectangular prism
= length x width x height
= 9 x 2 x 15
= 270 cm³
Thus, the volume of the given rectangular prism is 270 cm³.

Write this word sentence as an equation. 82 is the difference of a number b and 24
Answer:
106 - 24 = 82
Step-by-step explanation:
b = 106, solve 106 - 24 and you get 82.
Hope this helped.
Answer:
b/24=82
Step-by-step explanation:
Since the difference of an equation is the outcome of division we place 82 as the answer.
Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.

This graph shows the relationship between the number of cubic yards and total cost of topsoil at a garden shop.
Mulch
The equation, y=25x, represents
the cost, y, in dollars, of x cubic
yards of mulch at the garden shop.
Type an equation to represent the cost of the topsoil. Show your work.
and
How does the cost of the topsoil compare to the cost of the mulch?
Answer: y=30x
top soil is 5 more dollars than mulch
Step-by-step explanation:
to find y=30x
see what y equals when x equals 1
The cost of the topsoil is $5 more than the cost of the mulch.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, the equation, y=25x, represents the cost, y, in dollars, of x cubic yards of mulch at the garden shop.
From the, graph we have coordinates (1, 30) and (2, 60)
We know that, slope of points is (y2-y1)/(x2-x1)
Now, (60-30)/(2-1)
= 30
Substitute, m=30 and (x,y)=(1, 30) in y=mx+c, we get
30=30(1)+c
c=0
Substitute, m=30 and c=0 in y=mx+c, we get
y=30x
Per 1 cubic yard
Topsoil is y=30x=$30 and cost of the mulch is y=25x=$25
So, difference in cost is 30-25=5
Comparing cost in both the situation, the cost of the mulch is less than topsoil
Therefore, the cost of the topsoil is $5 more than the cost of the mulch.

Use the information from the graphs to write the equation in y=ab*^x
Answer:
1). y = 4(1.75)ˣ
2). y = (2)ˣ
Step-by-step explanation:
1). Let the equation of the given exponential graph is,
y = a(b)ˣ
Graph of the given equation passes through two points (0, 4) and (0+1, 4+3)
For point (0, 4),
4 = a(b)⁰
a = 4
For point (1, 7),
7 = 4(b)¹
b = [tex]\frac{7}{4}[/tex]
b = 1.75
Therefore, equation of the function is,
y = 4(1.75)ˣ
2). Similarly, equation of the second graph will be same in the form of
y = a(b)ˣ
Second graph passes through the points (0, 1) and (2, 4)
For (0, 1),
1 = a(b)⁰
a = 1
For (2, 4),
4 = 1(b)²
b = 2
Therefore, exponential function representing the graph will be,
y = 1(2)ˣ
y = 2ˣ
