Answer:

The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].

Step-by-step explanation:

A polynomial is a sum of algebraic monomials such that:

[tex]p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}[/tex]

Where [tex]n[/tex] is the degree of the polynomial and [tex]c_{i}[/tex] is the i-th coefficient of the polynomial. A 22nd degree polynomial has [tex]n = 22[/tex], so that given polynomial must added by a monomial with grade 22. Thus:

If [tex]p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}[/tex] and [tex]q = 12\cdot x^{22}[/tex], then we have:

[tex]p' = p+q[/tex]

[tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex]

The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].

I think the answer is $238.

71 x $3 = $213

2 + 3 = 5

5 x $5 = $25

$213 + $25 = $238

I hope this helps.

The total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of ticket for adult = $5.00

Cost of ticket for students = $3.00

Now, Total number of students = 71

Number of parents = 3

Number of teachers = 2

So, total adults = 3 + 2 = 5

Thus, Total cost of tickets for students = 71*5 = $355

and, Total cost of tickets for adults = 5*3 = 1$5

Therefore,

Total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum = Total cost of tickets for students + Total cost of tickets for adults

⇒ Total cost of ticket for a group = $355 + $5

⇒ Total cost of ticket for a group = $360

Thus, the total cost of ticket for a group of 71 students, 3 parents, and 2 teachers to attend the museum is $360.

Answer:

3/8

Step-by-step explanation:

1- 1/4 +(1/2 x 3/4)

1. subtract 1/4 to get 3/4 (how much time she has left in class).

2. multiply 3/4 by 1/2 to find how much half of 3/4 is.

3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.

Answer:

x-0,6x=20

0,4x=20/:0,4

x=50

Step-by-step explanation:

The original price of the jacket will be $50.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that after a 60% reduction, a jacket sold for $20. The original cost of the jacket will be calculated as below:-

Let the unknown number be x. Form the equation and solve for the value of x.

x-0,6x=20

0,4x=20/:0,4

x=50

Therefore, the original price of the jacket will be $50.

Answer:

7x-1

Step-by-step explanation:

14 + 7x - 15 = k

7x - 1 = k

Finding x,

14 + 7x - 15 = k

=> 14 + 7x = k + 15

=> 7x = k + 15 - 14

=> x = (k + 1)/7

So, 7 * (k+1)/7 - 1 = k

k + 1 - 1 = k

=> k = k

So the answer is true that 7x - 1

Answer: x>5

Step-by-step explanation: The Absolute Value term is |4x+6|

For the Negative case, we'll use -(4x+6)

For the Positive case, we'll use (4x+6)

-(4x+6) = 14

    Multiply

     -4x-6 = 14

    Rearrange and Add up

     -4x = 20

    Divide both sides by 4

     -x = 5

    Multiply both sides by (-1)

     x = -5

    Which is the solution for the Negative Case

(4x+6) = 14

    Rearrange and Add up

     4x = 8

    Divide both sides by 4

     x = 2

x=-5

x=2

tell me if I'm correct if u can

hope this helps :)

Step-by-step explanation:

Hey there!

M is the midpoint of SB.

Midpoint seperates the line into 2 equal parts.

I.e SM = BM.

So, If BM = 22.
