Answer:

[tex]b^{2} -2b+5[/tex]

Step-by-step explanation:

The equation that illustrates the identity property of multiplication is (a+bi) × 1 = (a+bi).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The identity property of multiplication states that when a factor is multiplied by 1 the result is the factor itself. Therefore, the equation that illustrates the identity property of multiplication is (a+bi) × 1 = (a+bi).

The equation of the area of the rectangle is w(2w + 5) = 50. Then the correct option is C.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches.

Let the width of the rectangle be w, then the length of the rectangle will be (2w + 5).

Then the area of the rectangle is given as

Area = l × w

Then we have

w(2w + 5) = 50

Step-by-step explanation:

Without buying points, the time that will be taken to break even will be 6 years.

The monthly mortgage payment will be $1,250. Buying 1 point at closing would reduce the payment to $1,236.

1 point= $1000

The time taken will be:

Monthly savings = 4250/1236 = 14

Time taken = 7

1000/14 = 71.4 months

71.4/12=5.95 years = ~6 years

Thus, The time that will be taken to break even will be 6 years.

Step-by-step explanation:

f(x) = 2x³ - px² + 2qx + q

(x - 3) is a factor of f(x)

⇒f(3)  = 0

2(3)³ - p*3² - 2q*3 +q = 0

Answer:

x =(24-√596)/2=12-√ 149 = -0.207

x =(24+√596)/2=12+√ 149 = 24.207

Step-by-step explanation:

Factoring  x2-24x-5

The first term is,  x2  its coefficient is  1 .

The middle term is,  -24x  its coefficient is  -24 .

The last term, "the constant", is  -5

Multiply the coefficient of the first term by the constant   1 • -5 = -5

Find two factors of  -5  whose sum equals the coefficient of the middle term, which is   -24 .

     -5    +    1    =    -4

     -1    +    5    =    4

Two solutions were found :

x =(24-√596)/2=12-√ 149 = -0.207

x =(24+√596)/2=12+√ 149 = 24.207

Answer:

40 in.^2

Step-by-step explanation:

Let's name the 2 shaded triangles: The left one is T1 and the right one is T2.

The area of a right triangle can be found using the equation (a*b)/2.


The 2 legs of T1 are 8 in. and 6 in. (from 10 - 4)
Area of T1 = [tex]\frac{8 * 6}{2}[/tex] = 24 in.^2

The 2 legs of T2 are 8 in. and 4 in.
Area of T2 = [tex]\frac{8 * 4}{2}[/tex] = 16 in.^2

Area of shaded region = 16 + 24 = 40 in.^2

The correct statement about the congruent figures is,

⇒ a reflection across the x-axis, followed by a translation 3 units to the right.

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

Three congruent figures are shown in the coordinate plane.

Now, From figure A and figure B,

Figure B is reflection across the x-axis, followed by a translation 3 units to the right across the figure A.

Thus, The correct statement about the congruent figures is,

⇒ a reflection across the x-axis, followed by a translation 3 units to the right.

Answer:

7.2

Step-by-step explanation:

We know that the radius is always the same throughout the entire circle. That is, any line going from the center of the circle to the edges = radius. In this problem, radius = 20.9 and so does the other 4 lines going from the center of the circle to the edge.

Since there is a right angle, we know that both triangles are right triangles where hypotenuse, c = 20.9 and b = 19.6. To solve for x, use pythagorean theorem:

a² + b² = c²

x² + 19.6² = 20.9²

x² + 384.16 = 436.81

x = √(436.81 - 384.16)

x = √52.65

x ≈ 7.256

Answer:

x-intercept is 8, meaning if you get 8 candy bars, you can get 0 popcorn bags.

y-intercept is 6, meaning if you get 6 popcorn bags, you can get 0 candy bars. When Jackie had 0 candy bars, she had 6 (y-intercept) bags of popcorn and when Jackie had 0 bags of popcorn, she had 8 (x-intercept) bars of candy.

Step-by-step explanation:

The y-axis represents the amount of popcorn bags she has and the x-axis has the amount of candy bars. When the linear line intercepts with either axis, at least one axis is always at zero.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Your homeowners policy has a premium of $150, a deductible of $5000, and a limit of $300,000.

And,  Your home suffers $500,000 in damages.

Now,

Since, Homeowners policy has a premium of $150, So we can pay the amount = 12 x 150

           = $1,800

And,  Homeowners policy has a deductible of $5000.

Then, The remain amount = $500,000 - $5,000

                                        = $495,000

Since, The limit of the policy = $300,000

Hence, The remain amount = $495,000 - $300,000

                                           = $195,000

After including the deductible amount we get;

Deductible amount = $195,000 + $5,000

                             = $200,000

Thus, He will pay $200,000.

b) ED and CD are equal in length (as shown by the markings)

c) 3: AE is perpendicular AB, AB is perpendicular to AE/AC, AC is perpendicular to AB

Answer:

7 to the left, and up 2.

Step-by-step explanation:

A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order.
