Please give me the correct answer ​

Answer:

The last part.

Step-by-step explanation:

The error is only at the last part. Basically the answer part.

The answer should be —

[tex]13 \sqrt{5} [/tex]

We don't multiply the square roots when adding or subtracting. That'd contradict the rules.

Here, we let the square root of five as x-term.

[tex] \sqrt{5} = x[/tex]

[tex]4 \sqrt{5} + 9 \sqrt{5} = 4x + 9x[/tex]

As we add up, we would get 13x. Thrn we convert x-term back to square root of five.

The answer would be —

[tex]13x \\ x = \sqrt{5} \\ 13 \sqrt{5} [/tex]

Remember that we don't multiply the square roots when adding or subtracting.

Answer:

1) 8x^2-10x-7

2) 30[tex]x^{9\\}[/tex]- 60[tex]x^{5}[/tex]

3) -10y^6 - 45y^5 + 25y^4

4) 30x^9 - 60x^5

5) 30x^9 - 60x^5

Step-by-step explanation:

1) (2x+1)(4x-7), we will multiply each term from the first parenthesis against every term in the second.

2x*4x = 8[tex]x^{2}[/tex], 2x*-7 = -14x

1(4x-7) = 4x-7.

8x^2-14x+4x-7 = 8x^2-10x-7

2) 10[tex]x^{5}[/tex](3x^4-6)

10x^5(3x^4) = 30x^9

10x^5(-6) = -60x^5

30[tex]x^{9\\}[/tex]-60[tex]x^{5}[/tex]

3) -5y^4(2y^2+9y-5)

-5y^4(2y^2) = -10y^6

-5y^4(9y) = -45y^5

-5y^4(-5) = 25y^4

-10y^6 - 45y^5 + 25y^4

4) 10x^5(3x^4 - 6)

10x^5(3x^4) = 30x^9

10x^5(-6) = -60x^5

30x^9 - 60x^5

5) (3y - 5z)(8y - 3z) =

3y*8y = 24y^2

3y*(-3z) = -9yz

-5z(8y) = -40yz

-5z(-3z) = 15z^2

24y^2 + 15z^2 - 49yz

Answer:

15

Step-by-step explanation:

(-7,0) and (8,0) are on the opposite side of origin of x axis

d = 8 - -7 = 15

Answer:

$88

Step-by-step explanation:

first, you find 20% of 57 which = 11.4

then subract it with 57 which looks like 57-11.4 = 45.6

= 45.6

first, you find 20% of 53 which = 10.6

then subract it with 53 which looks like 53-10.6 = 42.7

= 42.4

then you add them both  which = 45.6+ 42.4= 88

Answer:

Which of the following is NOT a triangle congruence postulate or theorem?

4) none of these

The choices which are not triangle congruence postulate are: 3)Angle Side Side

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

The reflexive property of congruence states that the considered geometric quantity, whether it be angle, line segment, or shape etc, is congruent to itself.

We need to find the choices which are not triangle congruence postulate or theorem.

The postulates that are used to prove the triangles congruent are,

1)Side Side Side

2)Side Angle Side

3)Angle side Angle

4)Angle Angle Side

5)Hypotenuse Leg

Other than these postulates none can be used to prove the triangles congruent.

3)Angle Side Side

Answer:

The answer is below

Step-by-step explanation:

A football team scored 3 touchdowns, 3 extra points, and 4 field goals.  

a. Write an expression to represent the total points the football team scored.  

b. Write another expression that is equivalent to the one written above.  

c. If each touchdown is worth 6 points, each extra point is 1 point, and each field goal is 3 points, how many total points did the team score?  

Solution:

a) Let t represent the number of points for a touchdown, e represent the number of points for the extra point and f represent the number of points for a field goal.

Total points = 3(t) + 3(e) + 4(f) = 3t + 3e + 4f

b) Total points = 3t + 3e + 4f   OR

Total points = t + t + t + e + e + e + f + f + f + f  OR

Total points = 3(t + e) + 4f

c) Total points = 3(t + e) + 4f = 3(6 + 1) + 4(3) = 3(7) + 4(3)

Total points = 21 + 12 = 33 points

The sum of the points the team has from different point gaining options

give the total number of points the team scores.

Reasons:

The number of touchdowns by the football team, t = 3

Number of extra points by the football team, e = 3

Number of field goals by the team, f = 4

Therefor, the total number of points, P = 3·t + 3·e +4.f

The specified editor is an equation editor, which can be used to write mathematical equations.

Using an equation editor, we have;

Answer:

2,721,911.31

Step-by-step explanation:

The formula for Population growth rate is given as:

P(t) = Po(1 + r)^t

Where

Po = Initial population = 1,300000

P(t) = Population after t years

r = growth rate = 3%

t = time in years = 25

Hence,

P(25) = 1,300,000(1 + 0.03)^25

P(25) = 2,721,911.3086

P(25) Approximately = 2,721,911.31

The projected population of the county be in 25 years is 2,721,911.31

Answer:

$837.5

Step-by-step explanation:

Step one:

given data

He makes a guaranteed salary of $400 per week

Commision on top of his base salary equal to 25% of his total sales for the week

Required

His total salary when he made sales of 25%

Step two

let us solve for 25% of $1750 made

=25/100*$1750

=0.25*$1750

=$437.5

Hence his total payment for the week will be

=$400+$437.5

=$837.5

Also, if the sales is $x his pay would be

let y be his pay

y=0.25x+400

Answer: I disagree

Step-by-step explanation:

I disagree with the statement from Cristian. When you raise a base number to a power of 3, it is possible for the number to get smaller.

For example, let's say our base number is negative 2, that is -2. Now let's find the cube of the number. This will be:

= -2^3 = -2 × -2 × -2 = -8

In this example, we can see that -8 is smaller than -2. This shows that the statement by Cristian is not correct.

Answer: A: 6:14

C: 15:35

E: 30:70

Step-by-step explanation:

From the question, we are given that the ratio of the number of adults to the number of children at the resturant is 3:7.

The choices below that represent an equivalent ratio goes thus:

A: 6:14

This can be represented as: 6/14. The common factor is 2 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

B: 8:12

This can be represented as: 8/12. The common factor is 4 and we reduce to lowest term which would be: = 2/3 = 2:3

This is not an equivalent ratio.

C: 15:35

This can be represented as: 15/35. The common factor is 5 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

D: 21:9

This can be represented as: 21/9. The common factor is 3 and we reduce to lowest term which would be: = 7/3 = 7:3

This is not an equivalent ratio.

E: 30:70

This can be represented as: 30/70. The common factor is 10 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

The correct options are A, C,and E.
