Answer:
it's the fourth answer
Step-by-step explanation:
(X-4) (X-4)
[tex]x^{2}[/tex]-4x-4x+16
[tex]x^{2}[/tex]-8x+16
The expression is x² + 8x + 16. The correct answer is a) x² + 8x + 16.
To multiply (x - 4)², we can use the concept of expanding a binomial squared. The formula for expanding a binomial squared is:
(a - b)² = a² - 2ab + b²
In this case, a = x and b = 4. Substituting these values into the formula, we have:
(x - 4)² = x² - 2(x)(4) + 4²
= x² - 8x + 16
Therefore, the correct option is a) x² + 8x + 16.

If Tn =n^+2n. Find third term of the sequence
Answers
Answer:
The third term of the sequence Tₙ = n² + 2n is:
T₃ = 15
Step-by-step explanation:
Given
As the sequence is given by
Tₙ = n² + 2n
To determine
The third term of the sequence
The third term of the sequence can be determined by substituting n = 3 in the sequence
Tₙ = n² + 2n
T₃ = (3)² + 2(3)
T₃ = 9 + 6
T₃ = 15
Therefore, the third term of the sequence Tₙ = n² + 2n is:
T₃ = 15

The perimeter of a dance floor is 44 feet.
The length is 8 feet less than twice the width.
Let I=length and w=width.
0 21 + 2w = 44
1 = 2w - 8
21 + 2w = 44
w= 21 – 8
0 21 + 2w = 8
1 = 2w - 44

olivia's passcode has 4 digit The second digit to the left is 3 times the first (left most) digit tHe number formed by the last (right most ) 2 digits is three times the second digit to the left.the sum of the digits is 21. what is olivia's pass code
Answers
Answer:
3927
Step-by-step explanation:
This is the answer my teacher gave me, I promise.
The four-digit passcode is 3927 and this can be determined by using the given data and by using the hit and trial method.
Given :
Olivia's passcode has 4 digits. The second digit to the left is 3 times the first (left most) digit.The number formed by the last (right most) 2 digits is three times the second digit to the left.The sum of the digits is 21.Let the four digits passcode be 'abcd'. Then mathematical expression that represents "The second digit to the left is 3 times the first (left most) digit" is given below:
b = 3a --- (1)
The mathematical expression that represents "the sum of the digits is 21" is given below:
a + b + c + d = 21 --- (2)
So, let a = 3, then b = 9, and the last two digits are 27. So, the number becomes 3927.
