Find the least common multiple of each pair of polynomials.
9(x+2)(2 x-1) and 3(x+2)
The least common multiple of the given polynomial 9(x+2)(2 x-1) and 3(x+2) is 3(x + 2).
According to the given question.
We have two polynomials 9(x + 2)(2x - 1) and 3(x + 2).
Since, we have to find the least common multiple of 9(x + 2)(2x -1) and 3(x+2).
As we know that, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by lcm(a, b), is the smallest positive integer that is divisible by both a and b. Since division of integers by zero is undefined, this definition has meaning only if a and b are both different from zero.
From the definition of least common multiple, we can say that the least common multiple of 9 and 3 is 3 and (x +2)(2x -1) and (x + 2) is (x + 2).
Thereofrore, the least common multiple of the given polynomial 9(x+2)(2 x-1) and 3(x+2) is 3(x + 2).

Evaluate the sum of the finite geometric series. Σ⁴ n=1 (2/3)ⁿ⁻¹
Sn = a(1 - rⁿ)/(1 - r) is the formula for the sum of a finite number of terms in a geometric series, where is the number of terms, is the first term, and is the common ratio.
The sum of the finite geometric series, Σ⁴ n=1 (2/3)ⁿ⁻¹ be 2.407.
What is meant by finite geometric series?The equation be Sn = a(1 - rⁿ)/(1 - r), where s is the total, a1 is the series's first term, and r is the common ratio, is a general formula for calculating the sum of an finite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.
Let the series be Σ⁴ n=1 (2/3)ⁿ⁻¹
Σ⁴ n=1 (2/3)ⁿ⁻¹ = (2/3)¹⁻¹ + (2/3)²⁻¹ + (2/3)³⁻¹ + (2/3)⁴⁻¹
= 1 + (2/3) + (2/3)² + (2/3)³
= 1 + (2/3) +(4/9) +(8/27)
Where, the first term is a = 1
common ratio be r = 2/3
n th term be n = 4
Let the equation be Sn = a(1 - rⁿ)/(1 - r)
substitute the values in the above equation, we get
S4 = 1(1 - (2/3)⁴)/(1 - (2/3))
S4 = 1(1 - (16/81)⁴)/(1/3)
S4 = (65/81) × 3
S4 = (65/27) = 2.407
Therefore, the sum of the finite geometric series, Σ⁴ n=1 (2/3)ⁿ⁻¹ is 2.407.

The vertex of a parabola is (−2, 6) and its y-intercept is (0, 2). The parabola is the boundary of a quadratic inequality. The boundary is drawn with a dashed line, and the interior of the parabola is shaded.
The compound inequality in this problem is represented by:
y > -(x + 2)² + 6.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the vertex is at (-2,6), hence:
h = -2, k = 6.
y = a(x + 2)² + 6.
When x = 0, y = 2, hence we use it to find a as follows:
2 = 4a + 6
a = -1.
Hence:
y = -(x + 2)² + 6.
The inequality is the interior of the parabola, hence values greater, and the parabola is dashed, hence it is an open interval and the inequality is given by:

635 is the 3 digit number Sean is thinking of.
What is a digit?A digit is one of the elements of a set that makes up a numeration system. Thus, in a certain context, a digit is a number. The digits in the decimal (base-10) Arabic numbering system are the constituents in the set 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Let a, b , c the digits of hundreds place, tens place and ones places.
Let the digit in the tens place be x, thus b = x
The digit in ones place is 25 less than the value of the digit in the tens place
c = x - 25
And finally, he digit in the hundreds place is 1 more than the digit in the ones place
a = (x - 25) +1
If a, b , c are digits of there respective places the the value of their digits are
a(100), b(10) c(1)
Now, b can be any no. which is more than 25 so as to make positive ones place, lets say 30
b = 30 = x
Thus x = 3, so
a = ( x - 25) +1
= ( 30 - 25) +1
= 6
c = 30 - 25

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.
Given the expression 3(a - b), substitute the value of the variable a and the value of variable b.
3(a - b)
