(a). The values of x for which f(x) = 8, are x = (-1 + √17) / 2 and x = (-1 - √17) / 2.
(b). The equation has no real roots, and f(x) never equals 5.
(c). The equation has no real roots, and f(x) never equals -5.
(d). The graph will confirm that there are two x-intercepts corresponding to the two solutions found.
What is algebraic value?
A general rule is that the algebraic expression should take any of the following forms: addition, subtraction, multiplication, and division. Bring the variable to the left side and the other values to the right side in order to find the value of x.
a.
To find the values of x for which f(x) = 8,
we need to solve the equation x² +10x +32 / x+5 = 8.
We can start by multiplying both sides of the equation by (x+5) to get rid of the fraction:
x² + 10x + 32 = 8(x + 5)
Expanding the right side:
x² + 10x + 32 = 8x + 40
Subtracting 8x from both sides:
x² + 2x + 32 = 40
Subtracting 32 from both sides:
x² + 2x = 8
Dividing both sides by 2:
x² + x = 4
Subtracting 4 from both sides:
x² + x - 4 = 0
We can use the quadratic formula to solve this equation:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 1, and c = -4.
So,
x = (-1 ± √(1² - 4 * 1 * -4)) / 2 * 1
x = (-1 ± √(1 + 16)) / 2
x = (-1 ± √17) / 2
Thus, the two solutions are x = (-1 + √17) / 2 and x = (-1 - √17) / 2. These are the values of x for which f(x) = 8.
b. To show that f(x) never equals 5, we need to show that there is no solution to the equation (x² + 10x + 32)/(x + 5) = 5.
Suppose there is such a solution, say x = a.
Then,
5(x + 5) = x² + 10x + 32
5x + 25 = x² + 10x + 32
-x² + 5x - 7 = 0
This is a quadratic equation and can be solved using the quadratic formula. However, we can see that the equation has no real solutions because the discriminant, b² - 4ac, is negative. Therefore, the equation has no real roots, and f(x) never equals 5.
c. To determine whether f(x) ever equals -5, we can follow a similar approach as in part b.
Suppose there is a solution to the equation (x² + 10x + 32)/(x + 5) = -5. Then,
-5(x + 5) = x² + 10x + 32
-5x - 25 = x² + 10x + 32
x² - 15x + -57 = 0
This is a quadratic equation and can be solved using the quadratic formula. However, we can see that the equation has no real solutions because the discriminant, b² - 4ac, is negative. Therefore, the equation has no real roots, and f(x) never equals -5.
d. To confirm the results of parts a, b, and c, we can plot the graph of the function f(x) = (x² + 10x + 32)/(x + 5) and sketch the result.
The graph of the function will show the x-intercepts and the y-intercepts and will also show any asymptotes.
The graph will confirm that there are two x-intercepts corresponding to the two solutions found.
Hence, (a). The values of x for which f(x) = 8, are x = (-1 + √17) / 2 and x = (-1 - √17) / 2.
(b). The equation has no real roots, and f(x) never equals 5.
(c). The equation has no real roots, and f(x) never equals -5.
(d). The graph will confirm that there are two x-intercepts corresponding to the two solutions found.

The area of the quare felid i 40,000 quared and we want to but a fence diagonally through the field. What hould the length of the fence be?
The length of the fence must be 282.84 ft.
Area of the field = 40,000 ft²,
The length of the fence will be equal to the diagonal of the square.
For a square of side length S, the area is:
A = S²
Substituting the values in the formula -
S² = 40,000 ft
Applying the square root on both sides -
S = √(40,000 ft²)
Calculating, the diagonal of a square of side length S is:
D = S x√2,
Substituting the values -
D = √(40,000 ft²) x √2
= √(80,000 ft²)

write the trinomial as a square of a binomial or as an expression opposite to a square of a binomial
24ab-16a^2-9b^2
Answer: The given trinomial, 24ab-16a^2-9b^2, can be written as an expression opposite to a square of a binomial.
To do this, we first factor out the greatest common factor of -4a, which gives us:
-4a(6b-4a-9b^2)
We can then factor -9b^2 as -(3b)^2, and group the remaining terms together:
-4a((3b-2a)^2-4a^2)
So the trinomial can be written as -4a( (3b-2a)^2 - 4a^2 ) which is an expression opposite to a square of a binomial (3b-2a)^2.

ABCD is a cyclic quadilateral in whicj side Ad and BC are produced to meet at E such that AE = BE .Prove that AB// DC
Answer: To prove that AB is parallel to DC, we can use the following steps:
Draw a diagram of the cyclic quadrilateral ABCD with the point E where sides AD and BC are produced to meet.
Since ABCD is a cyclic quadrilateral, all its interior angles add up to 360 degrees. Therefore, angle A + angle B + angle C + angle D = 360 degrees.
Since AE = BE, we can say that angles A and B are equal (by corresponding angles). Similarly, angles C and D are also equal.
Since angles A and B are equal and angles C and D are also equal, we can say that angle A + angle B = angle C + angle D.
Substituting this into our equation from step 2, we get: angle A + angle B + angle C + angle D = angle A + angle B + angle A + angle B.
Simplifying, we get: 360 = 2(angle A + angle B). This means that angle A + angle B = 180.
Since angle A + angle B = 180, we can say that angle A = angle B and angle C = angle D.
Now we can use the fact that corresponding angles are equal, then angle A = angle C and angle B = angle D.
We know that opposite angles of a parallelogram are equal, so we have proved that AB is parallel to DC.
It's important to note that this proof uses the fact that quadrilateral ABCD is cyclic, which means that the sum of its angles is equal to 360 degrees. It also uses the fact that opposite angles are equal in a parallelogram, and corresponding angles are equal when two lines are parallel.

The annual interest rate on the loan is 0.02 or 2%.
What is the annual interest rate?To find the annual interest rate on the loan, we need to use the formula for simple interest:
I = Prt
where:
I is the interest,
P is the principal (the amount of the loan),
r is the annual interest rate (expressed as a decimal),
t is the time in years
We know the following information:
I = $240
P = $4000
t = 3
We can use this information to set up the equation and solve for r:
240 = 4000 * r * 3
240 = 12000r
r = 240/12000
r = 0.02
