If all three of them together have a total of 520 kroner then bill would have 205 kroner

amounts of money that Alan, Bill, and Cassie have:

Let A be the amount of money that Alan has.

Let B be the amount of money that Bill has.

Let C be the amount of money that Cassie has.

From the problem, we know that:

A + B = 250 (equation 1)

B + C = 475 (equation 2)

A + B + C = 520 (equation 3)

We want to solve for B, the amount of money that Bill has.

One way to do this is to use equation 1 to solve for A in terms of B:

A = 250 - B

We can then substitute this expression for A into equations 2 and 3:

(250 - B) + B + C = 520

Simplifying this equation, we get:

C = 270

Substituting this value of C into equation 2, we get:

B + 270 = 475

Solving for B, we get:

B = 205

Therefore, Bill has 205 kroner.

One zero of the polynomial is given. Use it to express the polynomial as a product of linear factors over the complex numbers.

Given: f(x) = x^2 + 3x + 3 and zero: 3

Here's how to approach this problem:

The polynomial f(x) has a root of 3.

f(x) can be expressed as a product of two factors, where the first factor contains (x-3) as one of its roots, as follows:

f(x) = (x-3)(ax + b)

We can obtain the values of a and b by equating the coefficients of this equation to that of the given polynomial:

a + 3 = 1 (since coefficient of x in the given polynomial is 3)

-3a + b = 3 (since the constant term in the given polynomial is 3)

Solving these equations gives us a=-2 and b=9.

f(x) can thus be expressed as:

f(x) = (x-3)(-2x + 9)

Hence, the expression for the polynomial is f(x) = -(x-3)(2x-9).

The expression that represents the perimeter of the rectangle in centimeters is 45.2g - 30.6h.

Let's start by finding the length of the top and bottom sides, which are equal to the width. The width is given by (9.8g - 4.5h) centimeters, so the length of the top and bottom sides is:

2(width) = 2(9.8g - 4.5h) = 19.6g - 9h

Next, we need to find the length of the left and right sides, which are equal to the length. The length is given by (1.5g - 3.4h) centimeters, so the length of the left and right sides is:

2(length) = 2(1.5g - 3.4h) = 3g - 6.8h

Now that we have the lengths of all four sides, we can find the perimeter of the rectangle by adding them together:

Perimeter = length + width + length + width

Perimeter = (3g - 6.8h) + (19.6g - 9h) + (3g - 6.8h) + (19.6g - 9h)

The expression for the nth term of the sequence is,  Tn = 3n^2 - 7n - 1

To find an expression for the nth term of a quadratic sequence, we need to find a quadratic function that describes the sequence.

Let the nth term of the sequence be denoted by Tn. We can use the method of finite differences to determine the degree of the quadratic function that describes the sequence.

The first differences between the terms are 6, 10, 14, 18, 22. The second differences between these first differences are all equal to 4. This tells us that the sequence is quadratic, since the second differences are constant.

To find the quadratic function that describes the sequence, we can use the formula for the nth term of a quadratic sequence,

Tn = an^2 + bn + c

where a, b, and c are constants to be determined.

We can use the first three terms of the sequence to form a system of three equations,

T1 = a + b + c = -5

T2 = 4a + 2b + c = 1

T3 = 9a + 3b + c = 11

Solving this system of equations, we get:

a = 3

b = -7

c = -1

Therefore, the expression for the nth term of the sequence is

Tn = 3n^2 - 7n - 1

The value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.

What is the congruent angle?

When two parallel lines are cut by a transversal, the angles that are on the same side of the transversal and in matching corners will be congruent.

In an isosceles trapezoid, the base angles (the angles opposite the parallel sides) are congruent. Let's call each of these angles "a". Then, we have:

a = 3x + 10 (from one of the congruent angles)

a = 5x - 10 (from the other congruent angle)

Setting these two expressions equal to each other, we get:

3x + 10 = 5x - 10

Solving for x, we get:

2x = 20

x = 10

Now that we know the value of x, we can substitute it back into either of the expressions for "a" to find the measure of each base angle:

a = 3x + 10 = 3(10) + 10 = 40

Therefore, each base angle of the trapezoid has measure 40 degrees.

The other two angles of the trapezoid are the non-base angles (the angles adjacent to the parallel sides).

These angles are supplementary to the base angles, so each non-base angle has measure:

180 - 40 = 140

Therefore, the value of x is 10 and the trapezoid has two base angles with measure 40 degrees and two non-base angles with measure 140 degrees.
