Answer:

(4x2-3)(x2-5)

Step-by-step explanation:

(4x4-20x2)-(3x2+15)

4x2(x2-5)-3(x2-5)

(4x2-3)(x2-5)

The factorized expression of the polynomial is (4x^2- 3)(x^2 -5)

Polynomials are expressions that have more than one term

The expression is given as:

[tex]4x^4 - 20x^2 - 3x^2 + 15[/tex]

Factorize the expression

[tex]4x^2(x^2 - 5)- 3(x^2 -5)[/tex]

Factor out x^2 - 5

[tex](4x^2- 3)(x^2 -5)[/tex]

Hence, the expressions when multiplied that give the polynomial are (4x^2- 3) and (x^2 -5)

Answer:

c=42.25.

Step-by-step explanation:

A perfect square is number or expression that is multiplied by to numbers or expressions to make it. So for this, you would find one number that, added with itself with make -13. Which would be -6.5. So the answer will be determined by doing (x-6.5)^2 to get x^2-13x+42.25.   c = 42.25

The length of a segment is the number of units on the segment.

The ratio of line segment AC to line segment BC is 3 : 1

The coordinate points are given as:

[tex]\mathbf{A = (3,8)}[/tex]

[tex]\mathbf{B = (15,9)}[/tex]

[tex]\mathbf{C = (21,9.5)}[/tex]

The length of each segment will be calculated using the following distance formula

[tex]\mathbf{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]

So, we have:

[tex]\mathbf{AC = \sqrt{(3 - 21)^2 + (8 - 9.5)^2}}[/tex]

[tex]\mathbf{AC = \sqrt{326.25}}[/tex]

Also, we have:

[tex]\mathbf{BC = \sqrt{(15 - 21)^2 + (9 - 9.5)^2}}[/tex]

[tex]\mathbf{BC = \sqrt{36.25}}[/tex]

The ratio of AC to BC is represented as:

[tex]\mathbf{AC : BC = \sqrt{326.25}:\sqrt{36.25}}[/tex]

Divide through by [tex]\sqrt{36.25[/tex]

[tex]\mathbf{AC : BC = \sqrt{9} : \sqrt{1}}[/tex]

Evaluate square roots

[tex]\mathbf{AC : BC = 3 : 1}[/tex]

Hence, the ratio is 3 to 1

Answer:

The number 4 is in the tens place

Step-by-step explanation:

Use place value to find the answer (ones, tens, hundreds, thousands, etc.)

Answer:

Our problem is [tex]x^2-2x+6=0[/tex], but as we can see, we are unable to factor. We have to use the quadratic equation to solve.

[tex]x^2-2x+6=0[/tex]

[tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

Positive Quadratic Formula:

[tex]\frac{-(-2)+\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]

[tex]=\frac{2+\sqrt{4-24}}{2}\\=1+\frac{\sqrt{-20}}{2}[/tex]

Negative Quadratic Formula:

[tex]\frac{-(-2)-\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]

[tex]=\frac{2-\sqrt{4-24}}{2}\\=1-\frac{\sqrt{-20}}{2}[/tex]

Since both of our answers are the square root of a negative number, we know that the quadratic equation has no real solution.

*We could have also used the Discriminant Test to determine whether the quadratic equation has real roots or not. However, for our means, the quadratic equation seems enough.

Answer:

D. No real Solution

Step-by-step explanation:

Hello!

Let's use the quadratic formula: [tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

In our equation:

This comes from the standard form of a quadratic: [tex]ax^2 + bx + c[/tex]

Now, solve:

Since the radicand (-5) is negative, there are no real solutions. The correct answer is Option D.

Answer:

Step-by-step explanation:

I. The measure of the hypotenuse of triangle A is equal to 10 meters.

II. The measure of the hypotenuse of triangle B is equal to 10.30 meters.

Given the following data:

To determine the measure of the hypotenuse of triangle A, we would apply Pythagorean's theorem since the is a right triangle:

Mathematically, Pythagorean's theorem is given by the formula:

[tex]C^2 = A^2 + B^2\\\\C^2 = 6^2 + 8^2\\\\C^2=36+64\\\\C^2 = 64+36\\\\C^2=100\\\\C=\sqrt{100}[/tex]

Hypotenuse, C = 10 meters.

For Triangle B:

Triangle B has a height that is one (1) unit greater than triangle A:

Height B = 8 + 1 = 9 meters

Triangle B has a base that is one (1) unit less than triangle A:

Base B = 6 - 1 = 5 meters

To find the hypotenuse B:

[tex]C^2 = A^2 + B^2\\\\C^2 = 5^2 + 9^2\\\\C^2=25+81\\\\C^2=106\\\\C=\sqrt{106}[/tex]

Hypotenuse, C = 10.30 meters

From the above calculations , we can deduce that the measure of the hypotenuse of both Triangle A and Triangle B are different.

The number of pounds of apples that she has left will be 13/16 pounds.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A baker had 3 ¹/₄ pounds of apples. she used 3/4 to make an apple pie.

Convert the mixed fraction number into a fraction number. Then we have

3 ¹/₄ = 13/4

The number of pounds of apples that she has left will be given as,

⇒ 13/4 - (13/4)(3/4)

⇒ 13/4 - (39/16)

⇒ (52/16) - (39/16)

⇒ (52 - 39) / 16

⇒ 13/16 pounds

The number of pounds of apples that she has left will be 13/16 pounds.
