Which polynomial can be factored using the binomial theorem?
100x2 + 70x + 49
100x2 + 210x + 49
1,000x3 – 2,100x2 + 1,470x – 343
1,000x3 – 2,800x2 + 1,960x – 343
Answer:C
Step-by-step explanation:
The polynomial can be factored using the binomial theorem is
1,000x³ – 2,100x² + 1,470x – 343.
What is Binomial Theorem?Assertion that the sum of the nth power of the product of two positive integers a and b may be written as the sum of the n + 1 terms of the form for any positive integer n.
If a and b are real numbers and n is a positive integer, then
[tex](a + b)^n =^nC_0 a_n + ^nC_1 a_{n-1} b_1 + ^nC_2 a_{n-2} b_2 + ... 1.[/tex]
Given:
Using Binomial we can write
(a+ b)³ = a³ + b³ + 3a²b + 3ab²
and, (a+ b)² = a² + 2ab + b²
So, 100x²+ 70x + 49 and 100x² + 210x + 49 cannot be factors using Binomial Theorem because the correct expansion would be
(10x+ 7)² = 100x² + 140x + 49
and, 1,000x³ – 2,100x² + 1,470x – 343 can be factored using Binomial theorem.
As, (10x - 7)³ = 1000x³ -2100x² + 1470x - 343.

To see if it is possible, you will want to create an equation.
3(4x+2) = 6(2x+2)
As you can see, you will need to use the distributive property for this equation.
12x + 6 = 12x + 12
Remove 6 from both sides.
12x = 12x + 6
Divide 12 by both sides
x = x + 0.5
Because the answer wasn't x = x, the two plants won't ever be the same height. Even if you tried to subtract 0.5, you'd only get a negative 0.5 on the other side.

Answer:so it would be between 14/20
Step-by-step explanation:
Answer:
Step-by-step explanation:
Well first you should rearrange the equation to make it easier to graph. 8x-4y=16.
8x - 4y = 16.
8x +4y = 16 + 4y
8x -16 = 4y
Divide both sides by 4 to get y by itself.
2x - 4 = y
The y-intercept is -8 and the slope is 2x so the graph would look something like this.

Answer:
A. y = 8x
Step-by-step explanation:
y is the product, and x is one of the variables that will multiply another number to equal y. So x times a variable equals y, then y divide by x would equal that variable. And in the questions it gave us if y = 48 and x = 6. So we'll use that: 48/6 = 8, the variable is 8. 8 times 6 equals 48 so:
y = 8x

find the constant rate of change
Answer:
- 2 ft/ s
Step-by-step explanation:
The rate of change is the slope m of the line.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line
m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2
Rate of change is - 2 ft/ s

Given:
A right angled triangle.
To find:
The value of x.
Solution:
We have,
Base = x
Hypotenuse = [tex]\sqrt{5}[/tex]
In a right angle triangle,
[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]
For the given triangle,
[tex]\cos 45^\circ= \dfrac{x}{\sqrt{5}}[/tex]
[tex]\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}[/tex]
Multiply both sides by [tex]\sqrt{5}[/tex].
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x[/tex]
[tex]\dfrac{\sqrt{10}}{2}= x[/tex]
Therefore, the required value of x is [tex]\dfrac{\sqrt{10}}{2}[/tex].

Enter the value for x that makes the equation 1/2 (4x – 8) + 3x = 36 true.
Answer:
x = 8
Step-by-step explanation:
1/2(4x – 8) + 3x = 36
~Simplify left side
2x - 4 + 3x = 36
~Combine like terms
5x - 4 = 36
~Add 4 to both sides
5x = 40
~Divide 5 to both sides
x = 8
