The length of a rectangle is (x^2- 4x+2) feet and the width is (x+4) feet
Answer:
[tex]A=x^3-14x+8[/tex]
Step-by-step explanation:
Given that,
Length of a rectangle, [tex]l=(x^2- 4x+2)[/tex]
Width of a rectangle, [tex]b=(x+4)[/tex]
We need to find the area of the rectangle.
We know that,
Area of a rectangle = l × b
Substituting all the values,
[tex]A=(x^2- 4x+2)\times (x+4)\\\\=x^3+4x^2-4x^2-16x+2x+8\\\\=x^3-14x+8[/tex]
Hence, the area of the rectangle is [tex]x^3-14x+8[/tex].

Given a rational expression, identify the excluded values by finding the zeroes of the denominator.
x − 4
x2 + 2x − 24
The excluded values are x ≠ .
Step-by-step explanation:
In the rational fraction (x - 4)/(x² + 2x - 24),
x² + 2x - 24 is the denominator.
When x² + 2x - 24 = 0, (x + 6)(x - 4) = 0.
=> x = -6 or x = 4.
The excluded values for x are -6 and 4.

What is 54% of $789.56
Answer:
$426.36
Step-by-step explanation:
0.54 * 789.56 = 426.3624
hope this helps, pls mark brainliest :D
If you take 54% of the amount of $789.56, the resulting value would be $426.83.
As we know that percentage is a ratio that is stated as a fraction of 100.
To determine 54% of $789.56, we follow these steps:
Convert 54% to decimal form by dividing it by 100.
54% = 54 ÷ 100 = 0.54
Multiply the decimal value (0.54) by the dollar amount ($789.56).
0.54 × $789.56 = $426.8324
Round the result to two decimal places.
Rounding $426.8324 to two decimal places gives us $426.83.
Therefore, 54% of $789.56 is approximately $426.83.
This means that if you take 54% of the amount of $789.56, the resulting value would be $426.83.

Answer:
Step-by-step explanation:
y=l2−16k−4
Step 1: Flip the equation.
l2−16k−4=y
Step 2: Add -l^2 to both sides.
l2−16k−4+−l2=y+−l2
−16k−4=−l2+y
Step 3: Add 4 to both sides.
−16k−4+4=−l2+y+4
−16k=−l2+y+4
Step 4: Divide both sides by -16.

The table below shows that the number of miles driven by Nolan is directly proportional to the number of gallons he used.
Answer:
1835.16
Step-by-step explanation:
if you divide the miles driven by the gallons used, the answer is the # of gallons.
In this problem, 37.3 gallons is the gallons used so 49.2 x 37.3 = 1835.16

Answer:
C. ∠10
Explanation:
A theorem states that the two angle that are in the same side and are opposite to each other, they add up to 180°, which is supplementary.
1,a) Find a recursive formula for the sequence 1, 2, 6, 24, 120, . . . .
b) Find the sixth and the seventh terms of the sequence.
a) The n-th term in the sequence is the product of the first n natural numbers:
1 • 2 = 2
1 • 2 • 3 = 6
1 • 2 • 3 • 4 = 25
1 • 2 • 3 • 4 • 5 = 120
and so on. Recursively, the n-th term is a function of the (n - 1)-th term as
a(n) = n a(n - 1)
b) Using the rule above, the 6th and 7th terms are
a (6) = 6 a (5) = 6 • 120 = 720
and
a (7) = 7 a (6) = 7 • 720 = 5040
We want to find a recursive formula for the given sequence and then find the next terms in the given sequence.
the solutions are:
a) Aₙ = n*Aₙ₋₁
b) A₆ = 720 and A₇ = 5,040
We start with the sequence:
1, 2, 6, 24, 120, ...
a) Let's find the recursive formula.
If Aₙ represents the n-th term in the sequence, then we have:
A₁ = 1
A₂ = 2 = 2*1 = 2*A₁
A₃ = 6 = 3*2 = 3*A₂
A₄ = 24 = 4*6 = 4*Aₐ
A₅ = 120 = 5*24 = 5*A₄
So we can see the pattern, the recursive formula is just:
Aₙ = n*Aₙ₋₁
b) We want to find the sixth and the seventh terms of the sequence, we can use the recursive formula we got above.
A₆ = 6*A₅ = 6*120 = 720
A₇ = 7*A₆ = 7*720 = 5,040
The sixth term is 720 and the seventh term is 5,040

(1) Is the slope of the line having y=5 as its equation zero or undefined?
(2) is the slope of the line having x=-4 as it’s equation zero or undefined?
Answer choices: (A)the slope is neither zero or undefined. (B) the slope is undefined. (C) the slope is zero
Answer:
(1) The slope of the line having y = 5 as its equation is zero ⇒ (C)
(2) The slope of the line having x = -4 as its equation is undefined ⇒ (B)
Step-by-step explanation:
The line is a horizontal line if the y-coordinates of all points lie on it have the same valueThe equation of the horizontal line is y = b, b is the y-intercept (0, b)The slope of the horizontal line is zeroThe line is a vertical line if the x-coordinates of all points lie on it have the same valueThe equation of the vertical line is x = a, a is the x-intercept (a, 0)The slope of the vertical line is undefinedLet us use the rules above to solve the question
(1)
∵ The equation of the line is y = 5
→ That means the line is horizontal
∴ The line is a horizontal line
∵ The slope of the horizontal line = zero
∴ The slope of the line having y = 5 as its equation is zero
(2)
∵ The equation of the line is x = -4
→ That means the line is vertical
∴ The line is a vertical line
∵ The slope of the vertical line is undefined
∴ The slope of the line having x = -4 as its equation is undefined

What are permutation and combination?A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.
There are 18 football teams in a league.
Each team plays two matches against each of the other teams.
Then the total number of matches played by the teams will be given by the permutation.
