Answer:

(2x + 7yj)(2x - 7yj)

Step-by-step explanation:

Both 4x^2 and 49y^2 are perfect squares, and

4x^2 + 49y^2 is the sum of two squares.

There is a formula for factoring the difference of two squares:

a^2 - b^2 = (a - b)(a + b) (all real numbers here), but unless imaginary numbers are allowed, there's no formula for factoring the sum of two squares.

If imaginary numbers are allowed, then a^2 + b^2 factors into

(a + jb)(a - jb).

Following this pattern, 4x^2 + 49y^2 factors into (2x + 7yj)(2x - 7yj)

a^2 + b^2 = (a + b)(a

Answer:

$63,565

Step-by-step explanation:

We can solve this problem by using the equation provided to us:

[tex]s = 1,856y + 45,005[/tex]

We are solving for 10 years of experience so for y, we plug in 10 as shown below. Now lets solve for s:

[tex]s = 1,856(10) + 45,005[/tex]    Multiply 1,856 by 10

[tex]s=18,560+45,005[/tex]        Add the two numbers

[tex]s=63,565[/tex]

The salary offered to a potential employee with 10 years of experience is $63,565

Answer:

x=34

m∠S = 38

m∠T = 111

Step-by-step explanation:

Since the angles of a triangle should add up to 180, you can solve this equation:

31 + x+4 + 3x+9 = 180

the solution is x=34

Then the angles S and T can be found by substituting that value for x.

Answer:

Step-by-step explanation:

In a triangle, there are 180 degrees.

180- 31 = 149 degrees

(x + 4) + (3x+9) = 149

x=34

X+ 4 = 38

3x +9 =111

X =34, T=111, S=38

Its found in the second quadrant

Answer:

Step-by-step explanation:

2x + 5y = 14  -------------(i)

x + 3y = 16 ----------------(ii)

To eliminate x, multiply the second equation by  (-2)

(ii)*(-2)  -2x - 6y = -32

(i)           2x + 5y = 14       { Now add & x is eliminated}

                  - y = - 18     {divide by (-1)}

 y = 18

Plug in y =18 in Equation (i)

2x + 5*18 = 14

2x + 90 = 14

2x = 14 - 90

2x = -76

x = -76/2

x = -38

Answer:

Step-by-step explanation:

hello :

2x + 5y = 14...(*)

x + 3y = 16....(**)

multiply (**) by -2  :  -2x-6y=-32   ...(***)

add(*) and (***) : -y=-18   so y = 18

put this value in to (*) : 2x+5(18)=14

2x = -76

x = - 38

Answer:

5.81

Step-by-step explanation:

just did the problem

To find the value of 'a' given the angles and one side length using the Law of Sines, we calculate a ≈ 5.80 by substituting the values into the formula and solving.

To determine the value of a using the Law of Sines, we are given two angles A and B and the length of one side b. We use the equation provided:

\(\frac{\sin(A)}{a} = \frac{\sin(B)}{b}\)

Substitute the given information into the equation:

\(\frac{\sin(45^\circ)}{a} = \frac{\sin(77^\circ)}{8}\)

Next, cross multiply to solve for a:

\(8 \times \sin(45^\circ) = a \times \sin(77^\circ)\)

Finally, solve for a:

\(a = \frac{8 \times \sin(45^\circ)}{\sin(77^\circ)}\)

Use a calculator to find the approximate value of a, rounding to the nearest hundredth:

a \approx \frac{8 \times 0.7071}{0.9744}

a \approx \frac{5.6576}{0.9744}

a \approx 5.80

Answer:

b. 8.7

Step-by-step explanation:

The surface area of a triangular prism can be found by adding the areas of all faces. The triangular faces are calculated using the formula for the area of a triangle, and the rectangular faces are calculated using the given dimensions of the sides of the triangles. The total surface area is the sum of these areas.

The question is asking for the surface area of a triangular prism. In order to find this, you need to add the areas of all the faces. A triangular prism has 5 faces, 2 are triangles, and 3 are rectangles.

For the triangular faces, we use the formula for the area of a triangle which is 1/2ab, where a and b are the provided dimensions. Thus, the triangle's area is 1/2 * 20 cm * 25 cm = 250 cm². Since there are two of these, the total area is 500 cm².

The rectangular faces are more challenging since it seems like we don't have enough information. The rectangle is made up of the sides of the triangles, so one side is 20 cm. However, we don't know the length (C) of the triangle which would be the other side of the rectangle. Assuming C is given, multiply each corresponding side to get the area of each rectangle, and add all together.

The final step is to add the area of the triangles and rectangles together to find the total surface area of the prism.

Alphaville's Budget Surplus Model is [tex]-2x^2+ 500x[/tex]

Betaville's Budget Surplus Model is [tex]x^2- 100x + 10000.[/tex]

We want to determine the expression that shows how much greater Alphaville’s annual budget surplus is than Betaville’s for a particular amount of tax revenue.

[tex]-2x^2+ 500x-(x^2- 100x + 10000)\\[/tex]

Opening the brackets

[tex]-2x^2+ 500x-x^2+100x - 10000\\[/tex]

Collect like terms and simplify

[tex]-2x^2-x^2+100x + 500x- 10000\\=-3x^2+150x-10000[/tex]

The expression that shows how much greater Alphaville's Budget is:

Answer:

1 3/5 will be written as 8/5 in improper form.

Step-by-step explanation:

1 3/5 can also be seen as 1 + 3/5.

By making the 1 a like term, i.e. multiplying it by 5 (both numerator and denominator) we can add them as like terms.

1 will become 5/5.

5/5 * 3/5

= (5+3)/5

= 8/5

The fractional form of mixed number 1 3/5 is 8/5 .

Given,

Mixed number : 1 3/5

Here,

1 3/5 can also be seen as 1 + 3/5.

By making the 1 a like term, i.e. multiplying it by 5 (both numerator and denominator) we can add them as like terms.

1 will become 5/5.

5/5 * 3/5
