Select the correct answer. Which expression is equivalent to this polynomial? 9x^2 - 4
A. (3x + 2i)(3x - 21)
B. (3x - 2)(3x - 2)
C (3x + 2i)2
D. (3x + 2)2
Answers
Step-by-step explanation:
Given expression is :
[tex]9x^2-4[/tex]
We can write it as :
[tex](3x)^2-2^2[/tex]
Now using identity : [tex]a^2-b^2=(a-b)(a+b)[/tex]
Here, a = 3x and b = 2
So,
[tex](3x)^2-2^2=(3x-2)(3x+2)[/tex]
Hence, the given expression is equivalent to (3x - 2)(3x + 2) .
The solution to the equation A = 9x² - 4 is given by A = ( 3x + 2 ) ( 3x - 2 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 9x² - 4 be equation (1)
On simplifying the equation , we get
a)
Let the equation be A = ( 3x + 2 ) ( 3x - 2 )
A = 3x ( 3x ) - 3x ( 2 ) + 2 ( 3x ) - 2 ( 2 )
On simplifying the equation , we get
A = 9x² - 6x + 6x - 4
A = 9x² - 4
Therefore , the value of A is 9x² - 4
Hence , the equation is A = ( 3x + 2 ) ( 3x - 2 )

Gavin likes biking. He never misses a chance to go for a ride when the weather is nice. This week his goal is to bike about 65 total miles over four days. Each day, he wants to ride 1.5 times as far as he rode the day before. How far should he ride on each of the four days to reach his goal?
Question 1
To solve this problem, first you need to write the expressions for the distance Gavin needs to bike each day. Then, relate these expressions to create an equation that represents Gavin’s situation.
Part A
If x is the number of miles Gavin bikes on the first day, write an expression for the distance he should bike on each of the following three days.
Answers
The common ratio of 1.5 by which the distance Gavin rides on each subsequent day of 1.5 indicates;
Part A; Day 1; x, Day 2; 1.5·x, Day 3; 1.5²·x, Day 4; 1.5³·x
Part B; Gavin rides 8 meters on day 1, 12 meters on day 2, 18 meters on day 3, and 27 meters on day 4
What is a common ratio in a sequence?A common ratio is a value that is used to divide or multiply at each stage in a sequence.
The distance Gavin wants to ride each day = 1.5 × The distance he rode on the previous day
The common ratio of the distance Gavin plan to ride on each subsequent day is 1.5, therefore;
Part A; Where x represents the distance Gavin bikes on the first day, we get;
Day 1; Distance Gavin rides = x
Day 2; Distance he rides = 1.5·x
Day 3; Distance he rides = 1.5²·x
Day 4; Distance he rides = 1.5³·x
Part B; The equation that represents Gavin's situation can be found from the expression for the distance he rides each day by adding the distances equating the result to the distance Gavin wants to bike in total, as follows;
x + 1.5·x + 1.5²·x + 1.5³·x = 65
x·(1 + 1.5+ 1.5² + 1.5³) = 65
x = 65/(1 + 1.5+ 1.5² + 1.5³) = 8
x = 8 meters
The distance Gavin rides on each day are therefore;
Day 1; Distance, x = 8 meters
Day 2; Distance, 1.5·x = 1.5 × 8 = 12 meters
Day 3; Distance, 1.5²·x = 1.5² × 8 = 18 meters
Day 4; Distance, 1.5³·x = 1.5³ × 8 = 27 meters

Step-by-step explanation:
you can see that no matter how you rotate triangle be it can not get all the angles to match but if you were to fold it in half they are a perfect fit. :)
Triangle B is a reflection of triangle A so the given statement is incorrect.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given a triangle A.
If we rotate it about line segment l then it will not go to cover wholly triangle B.
If we rotate triangle A clockwise then the corresponding sides will not match.
If we rotate triangle A anti-clockwise then also corresponding sides will not match.
If we reflect the triangle A about line segment l then it will form an mirror image so if we fold triangle A over line l then it will completely cover triangle B.
Hence "Triangle B is a reflection of triangle A so the given statement is incorrect".

What is a scale factor?In Mathematics and Geometry, a scale factor can be calculated or determined through the division of the dimension of the image (new figure) by the dimension of the original figure (pre-image).
