The value of  m²+n²+p² is 46.

In mathematics, an identical element, also known as a neutral element, is an element of a set that, when subjected to a binary operation, leaves each element of the set intact. In algebraic structures like groups and rings, this idea is applied. Algebraic identities are algebraic equations that are true regardless of the value of each variable. Additionally, they are employed in the factorization of polynomials. Algebraic identities are employed in this manner for the computation of algebraic expressions and the solution of various polynomials.

Given Data

m + n+ p= 10

mn + np + mp = 27

For m² + n²+ p²

Using algebraic identities,

(m+ n +p)² = m² + n² + p² +2(mn + np + pm)

(10)² = m² +n² + p² + 2(27)

100 = m² + n² + p² + 54

100 - 54 = m² + n² + p²

46 = m²+n²+p²

The value of  m²+n²+p² is 46.

Answer:

let the number be x...therefore 1/3 of x equals to 1/3x

1/3x+5=6/5x....collect like terms

1/3x-6/5x=-5

0.3x - 1.2x = -5

-0.9x = -5

Divide both sides by coefficient of x....

X = -5/-0.9

The equation that Joey can use to determine how many months it will take to reach his goal will be 8 + 3x = 50 and the number of months is 14.

From the information, Joey's favorite present is the 8 baseball cards that he got from his dad and he has never owned a baseball card before this gift and he plans to collect 3 baseball cards each month until he has a total of 50 cards.

This will be illustrated as:

8 + 3x = 50

Collect like terms

3x = 50 - 8

3x = 42

Divide through 3

3x / 3 = 42 / 3

x = 14

The number of months is 14.

The multiplication expressions shown by the model are:

A multiplication expression is a mathematical statement that uses the multiplication operand with either number, variables, or a combination of the two to produce results.

The numbers or variables in a multiplication expression are known as multiplicand (the first number to be multiplied) and multiplier (the second number multiplying).

The result or solution of a multiplication operation is known as the product.

Thus, other possible multiplication expressions can be written out from the model because of the additive property of multiplication.

Step-by-step explanation:

The statement that is not true about the angles in the triangle is OPTION C. The measure of ∠K is 89°

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

From the diagram:

∠J + ∠K + ∠L = 180° (angles in a triangle)

Substituting:

(7x + 2) + (8x) + (4x + 7) = 180

19x + 9 = 180

x = 9

∠J = 7x + 2 = 7(9) + 2 = 65°

∠K = 8x = 8(9) = 72°

∠L = 4x + 7 = 4(9) + 7 = 43°

∠k ≠ 89°

The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24

The entire family can participate in tubing. Change into swimwear, rent a tube and a life jacket, and float down the river—that it's easy. Numerous outfitters provide transportation to the best waterways and rent tubes from Blue Ridge to Columbus, via Helen and Columbus.

The total cost of rent on tube = $360

Price of regular tube = $15

Price of cooler tubes = $7.5

Let the no. of regular tubes be and cooler tubes be y

The equation forms

15x + 7.5y = 360           ...1

As we can notice regular tube is twice the price of cooler tubes, sthe the equation forms

2(7.5) = 15

This means when y = 2, x = 1

cross multiply them and we find

2/y = 1/x

x/y = 1/2

x = y/2               ...2

Putting the value of x in eq 1, we get

15(y)/2 + 7.5y = 360

7.5y + 7.5y = 370

15y = 360

y = 360/15

y = 24

Putting the value of y in eq 1, we get

15x + 7.5(24) = 360

15x + 180 = 360

15x = 360 - 180

15x = 180

x = 180/15

x = 12

Thus, The no. of regular tube costing $15 were 12 and the cooler tube costing $7.5 each were 24.

Answer:

f(-10) = -299999

Step-by-step explanation:

Equation

f(x)= −3x^55+1

Given

x = - 10

Solution

You have to understand what f(x) means. When you put a value in for x, every x on the right is supplied with that value.

In this case I take the equation to mean what ever we are given in the brackets (in this case 10) is what goes into the x on the right. So the new equation is

f(-10) = -3*(-10)^5 + 1

(- 10) ^5 = - 100000

f(-10) = -300000 + 1

f(-10) = -299999

What is the unitary method of problem solving?
The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.

Given, for every 3 pencils, number of pens bought = 2
Therefore, every 1 pencil, number of pens bought = 2/3
Thus, for 21 pencils, number of pens bought = (2/3)*21 = 14
Therefore, total number of pencils and pens bought by Henry = 21 + 14 = 35.

18. x =   ± 4 √3 √5

Step-by-step explanation:

13. x³ = 54

x = ∛4

Factor 54: 2 x 27

∛54 = ∛2 x ∛27

∛27 = 3

answer: 3∛2

14. x² = 96

x = ±√96

96 = 6 x 16
√16 = 4

15. x³ = 88

x = ∛88
88 = 8 x 11
∛88 = ∛8 x ∛11 = 2∛11

16. x³ = -128 means x has to be negative

x = -∛128

128 = 64 x 2

∛128 = ∛64 x ∛2 = 4∛2

So x = -4∛2

⇒ A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The expression for the inequality will be;

⇒ 3(8 – 4x) < 6(x – 5)

Now, Solve the inequality as;

The expression for the inequality will be;

= 3(8 – 4x) < 6(x – 5)

Divide by 3 both side,

= 8 - 4x < 2 (x - 5)

= 8 - 4x < 2x - 10

Add 4x both side;

= 8 - 4x + 4x < 2x - 10 + 4x

= 8 < 6x - 10

Add 10 both side;

= 18 < 6x

Divide 6 both side;

= 3 < x
