The perfect square trinomial will be [tex]\rm x^2+14x+49[/tex] ,  [tex]x^2-24x+144[/tex]Expression 2 and 4 are correct.

A mathematical expression with three terms or three monomials is called a trinomial. Polynomials having only three terms are known as trinomials.

The second and fourth expression seems to be the perfect square let's check it.

Expression 2;

[tex]x^2 + 14x+49 \\\\ x^2+7x+7x+49 \\\\ x(x+7)+7(x+7)\\\\ (x+7)(x+7) \\\\ (x+7)^2[/tex]

Expression 4;

[tex]x^2-24 x +144 \\\\ x^2-12x-12x+144 \\\\ x(x-12)-12(x-12) \\\\ (x-12)^2[/tex]

Hence the perfect square trinomial will be [tex]\rm x^2+14x+49[/tex] ,  [tex]x^2-24x+144[/tex] .Expressions 2 and 4 are correct.

Pulling out like terms

3.1     Pull out like factors :

  -2x2 - 18x - 40  =   -2 • (x2 + 9x + 20)

Trying to factor by splitting the middle term

3.2     Factoring  x2 + 9x + 20

The first term is,  x2  its coefficient is  1 .

The middle term is,  +9x  its coefficient is  9 .

The last term, "the constant", is  +20

Step-1 : Multiply the coefficient of the first term by the constant   1 • 20 = 20

Step-2 : Find two factors of  20  whose sum equals the coefficient of the middle term, which is   9 .

     -20    +    -1    =    -21

     -10    +    -2    =    -12

     -5    +    -4    =    -9

     -4    +    -5    =    -9

     -2    +    -10    =    -12

     -1    +    -20    =    -21

     1    +    20    =    21

     2    +    10    =    12

     4    +    5    =    9    That's it

Answer:

length = 20 feet and width = 5 feet

Step-by-step explanation:

Volume is equal to volume = height * width * length. The questions tells us the total volume is 200 cubic feet and that the lenght is equal to length = 4w. Set up the equation 4w * w * 2 = 200 cubic feet. Multiply to get 8w^2 = 200 and solve for w.

An expression has numbers, variables, and mathematical operations. The other factor of the given binomial is a²+7a+10 except (a+5) is (a+2).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

To find the other factor of the binomial a²+7a+10, we can write it as,

[tex]a^2+7a+10\\\\=a^2+5a+2a+10\\\\=a(a+5)+2(a+5)\\\\=(a+5)(a+2)[/tex]

Thus, the other factor of the given binomial is a²+7a+10 except (a+5) is (a+2).

Based on the information the amount that Agnes paid as state income tax is $2,040.

Federal Income Tax is the tax system in the United States, levied and governed by Internal Revenue Services (IRS) which helps determine the tax that is charged on the income earned by individuals, corporates, and various other legal entities.

The first step is to calculate Agnes' federal taxable income.

Federal taxable income=$15449.60/0.284

Federal taxable income= $54,400

The second step is to calculate Agnes' state income tax.

State income tax=0.0375 ×$54,400

State income tax=$2,040

Hence, the amount that Agnes paid as state income tax is $2,040.

Answer:

Step-by-step explanation:

The markings on the figure show this to be a parallelogram. That means opposite sides are congruent. Because the sides are parallel, "alternate interior" angles are also congruent.

__

Angle y forms a linear pair with the one marked 83°, so is supplementary to it:

  y = 180°-83° = 97°

__

The angle marked y is an exterior angle to the triangle containing the angle marked (7x -5)°. As such, it is equal to the sum of the remote interior angles, the one marked (7x -5)° and the unmarked one that is congruent to (3x +32)°.

  (7x -5) +(3x +32) = 97 . . . . . angle relations in the left-side triangle

  10x +27 = 97 . . . . . . . collect terms

  10x = 70 . . . . . . . . subtract 27

 x = 7 . . . . . . . . divide by 10

__

The side marked Z is congruent to the opposite parallel side, so ...

  z = 19

__

The missing measures are ...

_____

Additional comment

You can also find the value of y by adding up the interior angles of the right-side triangle. The one not shown there is "alternate interior" to the one marked (7x -5)°, hence has the same measure. This gives ...

  (7x -5) +(3x +32) +83 = 180

Subtracting 83° from both sides gives the equation we used above.

  D) the point where the graph crosses the y-axis

Step-by-step explanation:

The "initial" value of a function is generally taken to mean the function value when the independent variable is zero.

On a graph of the profit function, that will be the y-intercept: the point where the graph crosses the y-axis.

__

The highest point on the graph will be the maximum profit.

The points where the graph crosses the x-axis will be where profit is zero, referred to as "break-even" points.

The lowest point on the graph will be where the profit is a minimum. That point may actually indicate a loss (negative profit).

The number of degrees that have been turned by the car when it travels from town a to town b will be 1080°.

From the information given, it was stated that it took a car 3 hours to travel from town a to town b and the wheel of a car completes a rotation.

In this case, a rotation is 360°, since there are 3 rotations, the degrees will be:

= 360 × 3

= 1080°
