how do i solve for x?

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

Answer:

Step-by-step explanation:

Answer:

3*2 = 6+9 = 15

Step-by-step explanation:

The required number is 2.

Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, nine more than three times a number is fifteen

Let the number be a

Converting the statement into mathematical expression,

9+3a = 15

3a = 6

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

Step-by-step explanation:

By using a^2+b^2=c^2, we can plot the numbers into the equation, 8^2+13^2=c^2. Then answering the exponents, it will equal 64+169=c^2. Add that together to get 233=c. Lastly, we have to square-root 233, which equals 15.26. Hope this helped!

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.

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.

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

Answer:

Parallel line: -4/9       Perpendicular line: 9/4

Step-by-step explanation:

This linear equation is written in standard form: Ax + By = C. First, we isolate the y variable to get the equation: y = -4/9x + 8/9. Now we notice that the slope of this line is -4/9. Parallel lines have the same slope, so the slope of the line parallel to this one is also -4/9. The slope of a perpendicular line is the negative reciprocal of the slope of this line, so the slope of a perpendicular line is 9/4.
